What does through mean?
Through is a versatile preposition and adverb whose central idea is passage or continuation from one point to another. It describes movement across a physical space, as in "walk through the garden," and extension from beginning to end, as in "read through a book." It can also indicate that something happens for an entire period, as in "through the winter," or that an action is completed despite difficulties, as in "get through a crisis." In its prepositional use, through introduces the route, means, or location involved: "travel through the tunnel," "speak through an interpreter," and "cut through the paper." The adjective through appears in combinations such as "through traffic" and "a through ticket." Although words such as across and throughout can sometimes overlap in meaning, through often suggests uninterrupted movement or passage from one boundary to another. Its flexibility makes it indispensable in descriptions of movement, time, communication, and completion.
Used to indicate passage from one side or place to another, the duration of a period, the means of doing something, or a point reached in space or time.

Where does through come from?
Through descends from Old English þurh, meaning "from end to end" or "during." It developed from Proto-Germanic *þurhą and ultimately from a Proto-Indo-European root associated with passing across or over. The English word thorough developed along the same broad etymological line, originally conveying completeness or an uninterrupted extent, while related forms such as thoroughfare and thoroughly preserve that sense of completeness.
