Till vs. Until – What’s the Difference?

Despite what many students learn in colleges and universities, brevity is a virtue in writing. Complicated sentences are sometimes necessary (and interesting), but they are harder to read and to understand. If you can state something simply and succinctly, you should do it.

The same principle applies to individual words: long, complicated words are sometimes necessary, but shorter ones are easier to understand and usually make your writing more fluid.

That is why many English words can be abbreviated or shortened into smaller words with the same meaning. Until is only two syllables, but even it can become till in the service of brevity.
