Hey kiddo, do you know what a "feature" is? It's a special thing that makes something unique or different from other things.
Now, let's talk about "semantic." This is a big word that means the meaning or idea behind something.
So when we put those two words together, "semantic feature" means special things that help us understand what a word means.
For example, let's think about the word "dog." Some semantic features of the word "dog" might be things like "four legs," "tail," "fur," "barks," "wags its tail," "breeds." All of these things give us a better idea of what a dog is and what it looks like.
Semantic features can be used to help us understand the meaning of lots of different words, especially if we are learning a new language. They are like little clues that help us piece together the meaning of a word.
