What is it called when an adverb comes immediately before the verb?

There isn't a specific term for an adverb that comes immediately before a verb. It's simply considered the normal position for an adverb modifying a verb.

However, some adverbs, particularly adverbs of frequency (e.g., always, often, never), are often placed before the auxiliary verb when there is one, like in:

* "He always comes late." (adverb before auxiliary verb "comes")

* "She never has been to Paris." (adverb before auxiliary verb "has been")

Keep in mind that word order can sometimes be flexible, and the placement of adverbs can change based on emphasis or stylistic choices.
