I remember being told that "teh" (a common misspelling of "the") is actually a proper (though very old and no longer in common usage) English word.
Teh was used as an example that if every single English word was included in a spell-checker it would decrease (the spell-checker's) utility (very few people know or use "teh", it's auto-corrected to "the").
I've checked both on-line and paper dictionaries and can't find it, can anyone confirm that it is an English word and what it's meaning is?
