Answer:
A grammatical morpheme is a word or word ending that makes a sentence grammatically correct.
Step-by-step explanation:
A grammatical morpheme can be an entire word or simply a group of letters that helps show another word's grammatical category, tense, number, etc. The definition may be strange, but it is easily understood with an example:
- I watch TV yesterday.
Is the sentence above grammatically correct? No. And that is because the word "yesterday" indicates that the action expressed by the verb happened in the past, but the verb itself is missing the grammatical morpheme that indicates the past tense. In this case, since "watch" is a regular verb, the morpheme that is missing is -ed:
- I watched TV yesterday.
