Until and till are both standard words meaning up to a stated time; 'til is an informal shortened form, while til without an apostrophe is often rejected in edited prose. The difficulty usually appears when a familiar form is used in a new context, where sound alone cannot reveal the correct choice. A reliable decision begins with meaning, sentence function, and audience.
Till is not an abbreviation of until, so it needs no apostrophe; choose until for neutral formality and till when its natural rhythm suits the sentence. The sections below turn that distinction into a repeatable editing method, with original examples that show how the choice works in conversation, professional writing, and polished prose.
