Common mistakesUsing 'clear' instead of 'clearly' as an adverb., Confusing 'clearly' with 'clearer' which is a comparative form., Omitting it in sentences where emphasis is needed.'Obvious' vs 'obviously': Confusing the adjective and adverb forms., Using in overly formal situations: It's too casual for very formal writing., Placing it too far from what it's describing: Should be close to the idea it clarifies.
Usage notesUse 'clearly' to emphasize that something is understandable or obvious. It is appropriate in both spoken and written contexts, but may seem overly formal in casual conversations.Use 'obviously' when something is clear or evident.
