| Common mistakes | Using 'age' instead of 'ages' for plural context., Not using it in appropriate casual situations., Confusing it with 'ages' meaning just a long time without the 'ago'. | Confused with 'once' for 'twice' or other frequencies., Using 'once' with present tense when referring to past events. | Using in formal contexts., Using without a time reference., Confusing with 'back in the day' which has a slightly different connotation. |
| Usage notes | Used in casual conversation to refer to a significant period of time that has passed. More appropriate in everyday speech than in formal writing. | Use 'once' to refer to something happening a single time in the past. It's neutral and often used in storytelling. It wouldn't be appropriate in highly formal writing. | Use in informal contexts to refer to events or situations from the past. It may not be appropriate for formal writing or speech. |
