clearly is typically an adverb that serves to modify verbs and adjectives in order to indicate distinctiveness or certainty. It is used to declare something emphatically and can be used to emphasize truth or accuracy.
1. He clearly understood the instructions given to him.
2. It is clearly evident that the project was a success.
3. The consequences were clear to me; I knew what I needed to do.
it is important to be aware that using 'clearly' too often can weaken the effect of the word. Furthermore, it is important to remember the difference between 'clearly' and 'obviously' as they are often used interchangeably but have slightly different meanings. Finally, the word 'clearly' should always appear before the word it is modifying.
