Here's the breakdown:
* Inflection: This refers to the various forms a verb takes to show tense, person, number, and mood. For example, "play," "plays," "played," "playing," etc. are all inflections of the verb "play."
* Infinitive: This is the base form of a verb, typically preceded by "to" (e.g., "to play").
Therefore, an infinitive is not an inflection. It's a distinct grammatical form.
