What?  That would mean that "ti" is a word also, it is just "to" misspelled.
Actually, "ti" is a word.  It's the seventh note in the solfeggio scale.  You know, the "Doe a deer" song?  Do, re, mi, fa, sol, la, ti, do. "Ti, a drink with jam and bread."  That's how you spell it. 
Knowing the solfege scale helps when needing to get rid of your last tile in scrabble-type games.
