It can mean via or by means of (learn through practice), across (walk through the park), throughout (awake through the night), because of (lost through carelessness) and, in American English, until (open Monday through Friday).
Spot the job first, then swap. The tables below sort another word for through by meaning, point out where a swap breaks the sentence, and cover the casual sense of being through with something.

Tone: thanks to, via, by means of
The chips move from relaxed to formal for the method sense. Thanks to is warm and casual, and it usually credits something good. Via is short and neutral, ideal for routes and tools. By way of sounds a little formal and is common for travel. By means of is precise and suits reports. By virtue of tops the scale and points to a quality as the cause: she won by virtue of her experience.
If the result is bad, avoid thanks to unless you are being ironic. Write because of or due to instead.

Through, throughout and thorough
Throughout stresses every part of a time or place: flags hung throughout the town. Through can mean the same for time, but throughout sounds more complete. Thorough is a different word, an adjective meaning careful and complete (a thorough check); do not mix up the spelling. Threw is the past tense of throw and only sounds like through.
Thru is a casual spelling seen on road signs and in texts. Keep it out of essays, resumes and emails to clients.
Swaps that go wrong
Across fits flat or open spaces, not tight ones: you squeeze through a gap, not across it. Via works for routes and channels but not for long efforts: write through years of training, not via years of training. Because of can replace through only when it names a cause; in learn through mistakes, the idea is method, so try by making mistakes. For more ways to show cause, see because synonyms.
