Consonant mutation

Hello kiddo! Today we're going to talk about a cool thing called consonant mutation.

Do you remember learning about the different sounds letters make in words? Well, these are called phonemes. Some languages, like Welsh and Irish, have something called "consonant mutation" where the first sound of a word can change depending on the situation.

Let's use the word "cat" as an example. If we add another word in front of it, like "big," the "c" in "cat" stays the same. But in Welsh, if we add another word in front of the equivalent of "cat," which is "cath," the "c" might change to a "g" or a "ch" sound! So instead of saying "cath," we might say "gath" or "chath."

This happens because certain sounds in Welsh are linked together in groups, and when we add a word in front of another word, it can cause them to switch around. It's like a secret code that only Welsh speakers know!

So that's what consonant mutation is all about. It's a fancy way of saying that some letters or sounds in a language can change depending on how the words are being used together. Pretty cool, huh?
