grammar
/ˈɡɹæm.ə(ɹ)/noun
The set of rules that describes how words are formed and combined in a language.
Example sentences
- “His vocabulary is excellent, but his grammar still needs work.”
- “This app checks your grammar before you send an email.”
Commonly misspelled 'grammer'; the word ends in -ar. Strictly it covers structure, not spelling or punctuation, though everyday complaints lump all three together.
