Here's why:
* Conjunctions connect words, phrases, or clauses. They include words like "and", "but", "or", "because", "so", etc.
* Adverbs modify verbs, adjectives, or other adverbs. They provide information about time, place, manner, degree, etc.
"Still" indicates that something continues to be the case. For example:
* "I still love to play video games." (modifies the verb "love")
* "It's still raining outside." (modifies the adjective "raining")
* "He walked still faster than the others." (modifies the adverb "faster")
