’til is not a word.
Please, use either until, or till. Some people think that ’til is an abbreviation of until, but this is folk etymology. “Till” is the older word by far, going back to at least Shakespeare’s day. For example:
John 21:22 (KJV) Jesus saith unto him, If I will that he tarry till I come, what to thee? Follow thou me.
Romeo and Juliet: I, v For I ne’er saw true beauty till this night.
Also note that “Till death us depart”, from the marriage liturgy in the Book of Common Prayer, dates back to 1549! It became “Till death us do part” in 1662.
Seeing advertisements for the old Fox show ’til Death always grated on me like fingernails on a blackboard. Luckily, like most Fox sitcoms, that show departed quite a while ago.
