Through is a multifunctional word whose most common usage is as a preposition indicating passage from one side to the other or completing a sequence, or as an adjective meaning finished or resulting in a certain state. In everyday speech, it often functions as a connective, linking ideas or outcomes. The sound sequence is unusual for many learners due to the subtle /uː/ vowel and the final /-uː/ vowel reduction before a voiceless consonant.
