Common mistakesConfused 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.Confused with 'formally' — 'formerly' relates to the past, while 'formally' relates to official contexts., Omitting it when describing past roles or states, which can lead to ambiguity.
Usage notesUse '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.Use 'formerly' to describe something that was true in the past but is no longer the case. It is more formal than saying 'used to'. Avoid in casual conversations.
