Here's a breakdown:
* Morpheme: The smallest unit of meaning in a language.
* Meaning: Can be either lexical (referring to a thing or concept) or grammatical (showing relationships between words).
Examples:
* Lexical morphemes: "cat," "dog," "run," "happy"
* Grammatical morphemes: "-s" (plural), "-ed" (past tense), "un-" (negative prefix)
Important points:
* Morphemes can be single words or parts of words: "cat" is a single morpheme, while "cats" is two morphemes ("cat" + "-s").
* A morpheme can be a word or a part of a word: "unhappy" contains two morphemes: "un-" and "happy."
* A word can contain multiple morphemes: "unbreakable" contains three morphemes: "un-", "break", and "-able".
