Lexical word

A lexical word is a big word that helps us understand the meaning of a sentence. It's like a puzzle piece that fits together with other words to make sense. For example, if we say "The dog ran," the word "ran" is a lexical word because it tells us what the dog did. But if we say "The fluffy ran," the word "fluffy" is not a lexical word because it doesn't give us important information about the sentence. It's just describing the dog. So, a lexical word is a special word that carries a lot of meaning and helps us understand what's going on in a sentence.
