* Adverb: This is the most common usage. It modifies a verb, adjective, or another adverb, indicating the intensity or force of the action or quality.
* Adjective: It can occasionally function as an adjective, particularly in informal language, describing something that is strong or intense.
Here are some examples:
Adverb:
* He strongly believes in the power of education. (modifies the verb "believes")
* The coffee is strongly brewed. (modifies the adjective "brewed")
* She argued strongly against the new policy. (modifies the adverb "argued")
Adjective:
* The team had a strongly worded letter to send to the board. (describes the letter's strength)
The context will usually determine which part of speech is intended.
