| Common mistakes | Incorrectly using 'ago' with future events., Confusing 'ago' with 'since' when discussing past time., Omitting the time expression, e.g., saying 'I saw him ago.' | Confusing 'before' with 'after'., Using 'before' to refer to an event that can only happen afterwards., Omitting the necessary clause or event after 'before'. | Confused with 'earliest' - 'earlier' compares two times, while 'earliest' refers to the first in a group., Using 'earlier' to refer to future events - it only applies to past events. |
| Usage notes | Use 'ago' to refer to a specific time in the past. It's typically used in informal and neutral contexts, but avoid using it in very formal writing or speeches. | Used to indicate a time prior to an event or action. Common in both spoken and written language. Avoid using it in extremely formal writing; in that context, consider 'prior to'. | Use 'earlier' to refer to a time before what is currently being discussed. It is neutral in tone. Avoid using it in highly formal contexts where specific time references are needed. |
