Hello hanuman I think you can take "here" in the "from here " as a noun, if you think it will be more convenient for your learning English. Traditional grammar classifies words based on eight parts of speech: the verb, the noun, the pronoun, the adjective, the adverb, the preposition, the conjunction, and the interjection. The lexical category adverb contains words typically modifying verbs, adjectives or other adverbs but it also contains many words that one would find difficult to classify into other categories.
