To a T
eamurray
I am looking for the origin of the phrase, "To a T" meaning a perfect fit; exact or precise.

example: After 50 years of marriage my grandfather can describe my grandmother to a T.

UPDATE: I was sniffing around a few other sites and found two possible suggestions for this phrase.

1. The "T" could be a reference to a T-square, a tool that provides very precise measurement of right angles. However, the phrase may have been in use prior to the invention of the T-square.

2. The "T" may stand for "Title" which refers to a small, precise brush stroke or printer's mark used in Hebrew manuscripts to differentiate between the character "dalet" and the caracter "resh".
