Are unconjugated verbs and infinitive the same thing?

Not exactly. While there's a lot of overlap, they're not completely interchangeable. Here's the breakdown:

Unconjugated verbs are verbs in their base form, without any grammatical modifications to indicate tense, person, number, or mood. For example:

* Walk

* Sing

* Read

Infinitives are a specific type of unconjugated verb form. They're usually preceded by "to" and can function as nouns, adjectives, or adverbs. For example:

* To walk

* To sing

* To read

Here's the key difference:

* Unconjugated verbs represent the base form of a verb, and can include forms like "to walk" and "running" (present participle).

* Infinitives are a specific unconjugated verb form that always starts with "to" and functions as a noun, adjective, or adverb.

In essence: All infinitives are unconjugated verbs, but not all unconjugated verbs are infinitives.

Example:

* Walk (unconjugated verb, not infinitive)

* To walk (infinitive, and also an unconjugated verb)

* Walking (unconjugated verb, present participle, not an infinitive)
