Quick Answer
The most common antonym for immediately is later. However, the best opposite depends on context. Other accurate antonyms include eventually, afterward, subsequently, gradually, someday, in due course, and at a later time.
While immediately means “without delay,” its opposite expresses delay, postponement, or action occurring after some time
What Does “Immediately” Mean?
Immediately is an adverb that means:
- Without delay
- At once
- Instantly
- Right away
- As soon as possible
It describes an action that happens with no waiting period.
Examples

Knowing the correct opposite of a word improves:
- Writing precision
- Speaking confidence
- Vocabulary variety
- Reading comprehension

- Creative storytelling
Instead of repeating one simple opposite, skilled writers choose words that match the exact situation.
