The word "specifically" is an adverb that is used to indicate something in a precise, exact, or clear manner. It is often employed to single out a particular detail or to clarify information in a way that eliminates ambiguity. For example, when you say "I want to learn about biology specifically," you mean you're interested in that subject in particular and not something broader.
The term "specifically" originates from the Latin word "specificus," which means "particular" or "of a kind." It comprised the prefix "speci-" related to species or sort and the suffix "-ally," which indicates the adverbial form.
