Question

infinitive also known as \full infinitive\ and sometimes \infinitive verb\ which sentence contains an infinitive? i want to learn french. they played basketball. she is singing loudly. the cat slept all day.

Explanation:

An infinitive is the base form of a verb, often preceded by "to". Let's analyze each sentence:

1. "I want to learn French.": "to learn" is a full infinitive (base verb "learn" with "to").
2. "They played basketball.": "played" is a past tense conjugated verb, not an infinitive.
3. "She is singing loudly.": "singing" is a present participle, not an infinitive.
4. "The cat slept all day.": "slept" is a past tense conjugated verb, not an infinitive.

Answer:

I want to learn French.
