Is it octopus or octopi? Mongoose or mongeese? English plurals can be tricky sometimes, and it's partly because of our fascinating history. So how do we choose which plurals to use when?

Daniel Midgley, Kylie Sturgess and Ben Ainsley (both individually and as a group) find the answers for this episode of Talk It Up!

Do you think of the number three as having a particular colour? Or do you associate letters with a certain sound? If so, you may be synaesthetic. Synaesthetes experience some senses in terms of other senses.

All of us are at least mildly synaesthetic; it's easy for us to think of things in other terms, and we speak as though this is so. We look into the insights that synaesthesia can provide into how we perceive language.

Anyone who loves words has probably noticed palindromes. They're words or phrases that read the same forward and backward.

But palindromes aren't just for fun. They have an interesting place in history, showing up in places as diverse as Ancient Rome and Bletchley Park.

Emoji are so hot right now. These days, it seems everybody is using those tiny pictures on their electronic devices.

But pictures can often be taken more than one way. And that can lead to misunderstandings. So how comprehensible are these emojis? Are they an international form of communication, or do they mean different things to different people in different places?

Some languages use speech sounds. Some languages use gestures. But a few languages use whistling. That's right; a surprising number of languages around the world are whistled, rather than spoken.

But how do they work? And do they operate like other languages do in our brains?

Daniel Midgley, Kylie Sturgess and Ben Ainsley pitch their questions for this episode of Talk It Up!

Shakespeare once asked: "What's in a name? that which we call a rose / By any other name would smell as sweet". 

And yet, it can be difficult to imagine ourselves by any other name.

We talk about different conventions of naming around the world, and show how we get from one nickname to another.

Do you live in a doggy-dog world? Do you sow your wild oaks? Or do you have to curve your enthusiasm?

These commonly misheard phrases are called eggcorns, and if you think your phraseology is up to stuff, you may get peeved at people who don't notice such Monday details. Sorry: mundane.

The spelling of English is a little funny sometimes.

English spelling is complicated by silent letters, double letters, influences from other languages, and just good old-fashioned sound change. So what are the chances that English spelling will be reformed?

Daniel Midgley, Kylie Sturgess and Ben Ainsley scrabble in the bag for tiles for this episode of Talk It Up!

Why can we have a big red balloon, but never a red big balloon?

We use adjectives - these describing words - all the time when we describe things as beautiful, blue, tenacious, or loquacious.

But as crazy as English can be sometimes, these adjectives show incredible discipline! Why do they always seem to line up in a way that makes sense?
