Answer:
A grammatical morpheme is a word or word ending that makes a sentence grammatically correct.
Explanation:
<u>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. </u>The definition may be strange, but it is easily understood with an example:
- I watch TV yesterday.
<u>Is the sentence above grammatically correct? No.</u> And that is <u>because</u> the word "yesterday" indicates that the action expressed by the verb happened in the past, but <u>the verb itself is missing the grammatical morpheme that indicates the past tense</u>. In this case, since "watch" is a regular verb, the morpheme that is missing is -ed:
- I watched TV yesterday.
