Pro Tip

Timing Clarity

Use 'just about to' to emphasize that an action was imminent but interrupted. Pair with 'when' to show interruption: 'I was just about to eat when the doorbell rang.'

Gold Rule

Tense Consistency

Always use 'just about to' with a verb in the base form (infinitive without 'to'). Never add 'to' after 'about to': 'just about to go' (correct), 'just about to to go' (incorrect).

Word Origin

The phrase combines 'just' (meaning 'exactly' or 'very recently') with 'about to' (indicating proximity in time). 'About' derives from Old English 'on būtan' (on the outside of), evolving to mean 'near in time or position'. The construction emerged in Middle English as a temporal expression.

Usage Notes

Common in spoken English to set up a contrast (e.g., 'I was just about to... when...'). Avoid using with past perfect tense ('had just about to' is incorrect).
