Definition from Wiktionary, the free dictionary
- Forms a future tense.
- Forms a tense future to some past time.
- I was going to cut the grass, but it started raining.
- Going is technically a present participle which may be followed by an infinitive with “to”. However, this phrase is commonly interpreted as a modal or auxiliary verb.
- The future formed with "going to" (or "gonna") differs from that formed with "will". It usually indicates something already planned, an intention, or something that is bound to happen.
- It is sometimes used without the main verb (in the infinitive):
- "Did you cut the grass?" "No, I was going to, but it started raining."
- In spoken English "going to" is often replaced by "gonna", but only when forming a future, not in a sentence like "I'm going to New York" (although this might be pronounced "I'm goin' to New York").
will (future tense)
- to (particle)
