scavenger

A scavenger is a creature that survives by picking through leftovers, scraps, rubbish and dead things. Think vultures circling roadkill, foxes raiding bins or that friend who says they’re on a diet then eats all your chips.

You wouldn’t want to mess with that, would you?

‘Scavenger’ didn’t always conjure up images of vultures and bin-diggers though. In fact, its origins are less animal-ly and more administrative. It comes from ‘scavager’, which is from an Anglo-French word, ‘scawageour’, which means ‘collector of scavage’. WTF is scavage, I hear you say. Well, in ye olde medieval times, ‘scavage’ was a tax (grrr) levied by towns and cities on goods sold by non-residents. This was actually a fairly well-intentioned tax, as it was supposed to give resident merchants a competitive advantage.

You might think that scavenger came to mean one who roots through crap as a way to insult the taxman (or woman). But it actually happened because the officers in charge of collecting this tax were later made responsible for keeping streets clean (I’m not entirely sure how these two skills became interchangeable, but I suspect it was to do with budget cuts).

Over time, ‘scavenger’ stopped referring to people altogether (apart from the chip guy I mentioned above) and settled on animals that lived off refuse, carrion and other unappetising delights.

Fun scavenger facts:

• vultures have stomach acid that’s so strong it can digest anthrax, botulism and cholera. I don’t want to know how they found this out. They also have a diet that’s 90% bone. Yum

• hyenas are often mistaken for scavengers, but they actually hunt most of their food – spotted hyenas (the most well-known type) catch up to 80% of their food themselves and have a hunting success rate that rivals lions. They are, however, very opportunistic and won’t turn down an easy meal if they happen to find one on the floor. Same as me, to be fair

• my parents once saw a seagull steal a piece of cake with a whole fork in it – a metal one too.

It’s worth saying that scavengers play a vital role in our ecosystem by getting rid of all the dead crap on the ground. So without them, the world would be a much messier place.

psychrophilic

You’ve probably noticed that stuff is really expensive these days. And one of the most expensive things is staying warm (as I type this I’m wearing two jumpers, a scarf and gloves, and I have an extra-long hot water bottle wrapped round me – still cold though). Thanks to soaring energy prices, we’ve all had to become psychrophilic.

As you’ve probably guessed, psychrophilic is a scientific term for organisms that love living in cold environments – think glaciers, deep-sea trenches and the like. They’re usually bacteria, fungi, microbes and other tiny little critters like that.

‘Psychrophilic’ first turned up as a scientific term in the early 20th century. It’s a combination of two Greek words – ‘psychros’ meaning ‘cold’ and ‘philos’ meaning ‘loving’. Sometimes etymology really isn’t rocket science.

The opposite of psychrophilic is, of course, thermophilic. These heat-loving organisms thrive in temperatures above 45°C. Psychrophilic and thermophilic organisms are often also extremophiles, another former word of the week.

Psychrophilic organisms are super helpful to science. Here are a couple of examples:

Antarctic krill in action – actual size, around 6cm

• colwellia psychrerythraea: a bacterium found in the deep sea, particularly in the Arctic and Antarctic. It produces proteins that stay active at really low temperatures, which is handy for things like food preservation

• pseudoalteromonas haloplanktis: this is another type of bacterium which also thrives in the Antarctic. It’s studied for its enzymes, which we use to clean clothes in cold water

• Antarctic krill: this tiny shrimp-like crustacean also lives in the freezing waters around Antarctica. It’s what’s known as a keystone species, which means it plays a critical role in maintaining the structure and balance of its ecosystem. Without this unassuming little creature, the Southern Ocean ecosystem would be completely devastated, as would the wider environment. The best things really do come in small packages. (Oh, and just to end on a positive note, you’ll be pleased to hear that Antarctic krill is one of the few species in the world that isn’t endangered. So the Southern Ocean ecosystem should be okay for now. Apart from all the climate change. Sorry.)

marcescence

Have you ever noticed a leaf clinging stubbornly to a tree, when all its other leaf friends have long fallen off? There’s a word for that. Marcescence is where something, usually plant matter like leaves or flowers, withers but doesn’t fall off. I can relate.

Oaks and beeches are classic examples of trees with marcescent leaves, which often stay in place for the whole of winter. It’s most common in juvenile plants too. Stroppy teenagers, eh?

Marcescence has its roots (HAHAHAHA) in Latin. Marcēscere means ‘to wither’ or ‘begin to decay’. This comes from marcēre, meaning ‘to be weak or withered’.

Marcescence first made its way into English in the mid-18th century when the study of botany was flourishing (I can’t help myself, sorry), and scientists were coming up with lots of neologisms to describe the natural world. That’s just a fancy way of saying that they were inventing lots of new words.

So how does marcescence happen? Let’s do some science for a sec. In most deciduous trees, a process called ‘abscission’ causes leaves to fall off in autumn. A specialised layer of cells forms at the base of the leaf stem to make this happen. But in marcescent trees, this process doesn’t fully complete, leaving them partially attached. Why? Well, it seems that no one’s entirely sure. There are a few theories though…

1. It’s for protection: the hanger-on leaves might protect new buds from weather or things trying to eat them. Marcescence is more common in younger trees and on lower branches, which adds credence to this defence theory.

2. They provide food for the soil: fallen leaves are great for promoting new growth as they rot. The theory here is that by falling off later, marcescent leaves will carry on providing this goodness to their tree long after their pals have gone to the big forest in the sky

3. To send water to the base of the tree: these leaves could act as a sort of snow fence, slowing down the white stuff and sending moisture to the bottom of the tree where it’s needed most.

There you go. Now you can casually say something like ‘there are so many marcescent leaves around this season’ on your next wintry walk and look well clevs. You’re welcome.

(Oh, and I saw this lovely word in the excellent Tone Knob newsletter, written by my equally excellent ex-colleague Nick Parker. If you’re even a bit interested in writing and tone of voice, it’s well worth signing up. You can do that here.)

filipendulous

If something is filipendulous, it means it’s hanging by a thread or a filament. It’s most often used to describe things that appear suspended by delicate or slender attachments, and look like they could drop at any moment. Like a spider suspended by a single thread. Or my sanity.

Like many of our words (especially the complicated ones), filipendulous comes from Latin. It’s a combination of the Latin word ‘filum’ meaning ‘thread’, and ‘pendere’ which means ‘to hang’.

You’re most likely to come across the word filipendulous in botany, where it’s used to describe plants with structures on fine stalks or threads. There’s actually a genus of plants called Filipendula containing 12 species of perennial herbaceous plants. That includes meadowsweet and dropwort, and the excellently named queen-of-the-forest (Filipendula occidentalis) and queen-of-the-prairie (Filipendula rubra), both of which are native to North America.

Filipendula species are food plants for the larvae of some Lepidoptera (AKA butterflies and moths) species, including the emperor moth, one of the biggest in the world. The largest emperor moth has a wingspan of between 15 and 20cm (6 to 8 inches). Yeesh. (I’ve literally just finished reading ‘The Travelling Bag’ by Susan Hill which makes this fact particularly freaky. If you know, you know.) These moths live in Europe, but haven’t made it across the Channel to us (YET). Having said that, our largest moth is the privet hawk moth, which can get up to a not-too-shabby 12cm (4.7in) wingspan.

You wouldn’t want either of those flapping round your bedroom light, would you?

yonic

I expect you know what ‘phallic’ means. But you’ve probably never heard of ‘yonic’, which is basically the female equivalent* (shakes fist at patriarchy) – an adjective that describes objects or symbols that resemble or represent the female genitalia, particularly the vulva.

‘Yonic’ is derived from a Sanskrit word, ‘yoni’ (योनि), which means ‘womb’, ‘uterus’ or ‘vulva’, as well as ‘source’. In various Eastern religions and spiritual traditions, the yoni is revered as a symbol of divine feminine energy and fertility, and the origin of life. The concept of the yoni is often associated with the goddess Shakti in Hinduism, representing the creative and nurturing aspects of the universe. Yoni and linga (the masculine version) iconography is found in Shiva temples and archaeological sites across the Indian subcontinent and southeast Asia.

The yoni may well be the oldest spiritual icon not just in India but in many ancient cultures. It’s only here in the West that we’ve traditionally treated feminine sexual organs and sexuality as taboo – in Indic religions (i.e. Hinduism, Buddhism, Jainism and Sikhism) and other similar ancient cultures, the yoni has long been seen as as a deep philosophical and cosmic truth that represents feminine power and potential. It’s closely linked with the natural cycles of the moon, earth and life itself. Take that, patriarchy.

Roses are often considered a yonic symbol, which seems a bit odd to me as men often give them to women as a romantic gesture. Maybe they should be giving us more phallic flowers. Like the phallus impudicus, for example, AKA the common stinkhorn, a fungus renowned for being shaped like a penis and for having an absolutely horrible smell. Hmmm, maybe this is why I’m single…

*Which presumably gets paid 13% less than her male counterpart.

haggard

Today we use the word ‘haggard’ to describe someone who looks like crap, usually because they’re sick, under some sort of emotional strain or incredibly hungover. But it didn’t always mean that.

‘Haggard’ has its roots in falconry. In case you’re not familiar with that, falconry, also known as hawking, is a traditional practice of hunting with trained birds of prey, usually falcons, hawks or eagles. It dates back over 4,000 years and has been practised by various cultures around the world, including ancient Mesopotamia, China, Egypt and medieval Europe.

While the relationship between the falconer and the bird is built on trust and respect, traditionally these birds weren’t bred in captivity – they were either taken from the nest when very young or trapped as adults. And that’s where our word comes in. A bird trapped as an adult was called a ‘haggard’, from the Middle French word ‘hagard’, meaning ‘wild’ or ‘untamed’. Over time, the meaning of ‘haggard’ has evolved to describe someone who looks exhausted, or wild and unkempt due to fatigue or stress.

In 2010, UNESCO recognised falconry as an ‘Intangible Cultural Heritage of Humanity’ which acknowledges its cultural significance. These days it’s still practiced as both a sport and a conservation tool, and also to control pest birds and animals in urban areas. It’s also very well regulated to make sure the birds are treated ethically and that wild populations aren’t affected.

(The return of the goshawk as a breeding bird to Britain is due in large part to these birds escaping from falconers – the previous population was wiped out by gamekeepers and egg collectors in the late 19th and early 20th centuries.)

We get a few other words and phrases from falconry too:

• lure – from a device used to recall hawks

• rouse – this used to mean ‘to shake one’s feathers’, although we now use it for waking up

• pounce – previously this referred to a hawk’s claws, then to birds springing or swooping to catch prey

• to turn tail – AKA to fly away.

peristeronic

No, I haven’t spelled (spelt?) ‘prehistoric’ wrong. If something or someone (god forbid) is peristeronic then it means it or they relate to or resemble a pigeon.

The etymology is pretty straightforward – the ancient Greek word for dove or pigeon is ‘peristera’. Both of these birds come from the columbidae family. We get a couple of nice words from that as well:

• ‘columbarium’ – another word for a pigeon loft or a dovecote (I wonder why pigeons get lofts but doves gets cotes? Seems a bit racist), and also any type of vault which has niches for storing urns in it

• ‘columbine’ – which means of or relating to a dove, in innocence, gentleness, colour and so on. It’s also the name of one of the stock characters in commedia dell’arte (a form of popular theatre from 16th-century Italy that Inside No. 9 used as a basis for an episode that most people – including me – didn’t understand).

Time for pigeon facts. Pigeons are monogamous and mate for life. Mum and dad pigeons share parental responsibilities equally, meaning they’re already far more evolved than most humans (and I bet there’s no gender-pay gap). They’re also pretty clever. Aside from their awesome navigational abilities – an Oxford University study found that pigeons use manmade landmarks as signposts and often fly along roads and motorways, even changing direction at junctions – they can apparently recognise all 26 letters of the English alphabet and solve problems (I think I need a pigeon assistant).

GI Joe. He’s not dead, he’s resting.

Homing pigeons were used extensively during the First and Second World Wars for communication and reconnaissance. In fact, pigeon USA43SC6390, AKA GI Joe, saved the lives of the inhabitants of an entire Italian village, and the British troops who were occupying it, on 18 October 1943. Air support had been requested to deal with German soldiers in the village (called Calvi Vecchia). GI Joe flew 20 miles in 20 minutes to deliver a message that the British 169th (London) Infantry Brigade had captured the village, arriving just as the planes were getting ready to take off to bomb the target. He saved the lives of at least 100 men. GI Joe was given the Dickin Medal (which sounds rude but isn’t) for ‘the most outstanding flight made by a United States Army pigeon in World War II’.

I’m not crying, I’ve just got something in my eye.

‘Feed the birds’ from Mary Poppins – the dirty old bird lady always makes me well up.
