What part of speech is “especially”

adverbs are used to answer questions like 'how,' 'where,' and 'when,' and provide detailed information about the action or quality being described. In the case of 'especially,' it's used to emphasize a particular action or quality among many. Its use implies that the action or quality being emphasized is more marked than the others.

generally, 'especially' is placed immediately before the word or phrase it is emphasizing, although it can come after non-emphasized words or phrases and/or at the beginning of a sentence. When used in a modified noun phrase, it comes after the noun it is modifying and before the adjective, adverb, or prepositional phrase that is describing it.

1. I especially like the way your presentation highlighted the importance of collaboration.

2. His diet consists mainly of vegetables, especially greens.

3. Everyone in class was sleeping, especially Patrick.

some writers may use 'especially' as a synonym for 'specifically,' but this is incorrect. 'Especially' implies emphasis, while 'specifically' denotes precision or exactness.
