In the English language, the word like has a very flexible range of uses, ranging from conventional to non-standard. It can be used as a noun, verb, adverb, adjective, preposition, particle, conjunction, hedge, filler, and quotative.
From Middle English liken, from Old English līcian (“to please, be sufficient”), from Proto-Germanic *līkōną, *līkāną (“to please”), from Proto-Indo-European *līg- (“image, likeness, similarity”). Cognate with Dutch lijken (“to seem”), German gleichen (“to resemble”), Icelandic líka (“to like”), Norwegian like (“to like”), Albanian ngjaj (“I resemble, I'm alike”) from archaic nglâj.
