Nonconcatenative morphology

Nonconcatenative morphology is like playing with Legos, but instead of just snapping pieces together, you have to change the shape of the Legos to get the word you want.

Let's say you want to make the word "cats". You can't just snap together "cat" and "s". Instead, you have to change the "a" to an "i" and add an extra "t". This might seem tricky, but it's actually very common in languages like Arabic and Hebrew.

It's like a game of word Jenga - you have to carefully stack and change parts of the word to get the overall meaning you want. And just like Jenga, if you mess up one piece, the whole word can come tumbling down!
