he still lives in that house

es, what a good question! “Still” is a part of speech that is called “adverb” which modifies the verb “lives”.
In general adverbs occur in many forms i.e. adverbs of time, manner, situation etc.
That “adverbs” modify “verbs” means that they show intensity, severity, frequency, colour of the verb at most and adjective at the least. At present, the focus is on “still” as “adverb” of time the act living has been in place since some time in the past and may be in the future.
It's interesting that the determination of the parts of speech may be based on relative position of a word before or after it. This leads to knowing the function a word performs in a sentence, clause and a phrase.
“Still” is between the pronoun“he” and the verb “lives” and therefore reflects on the two. “Still” highlights “lives”.
