In Late Latin and Old French, -t- before -e- and -i- acquired the "s" value of -c- and words appeared in both spellings (nationem/nacionem) and often passed into Middle English with a -c- (nacioun). In most of these the spelling was restored to a -t- by or during early Modern English. Edmund Coote's "English Schoole-maister" (1596) still has malicious/malitious; and a few words well-established in the old spelling (space, place, coercion, suspicion) resisted restoration.

The pronunciation shift in -tu- words in southern English, to "-shu-" (nature, actually), was noticed by c. 1900.

To cross one's t's (and dot one's i's) "be exact" is attested from 1849. Phrase to a T "exactly, with utmost exactness" is recorded from 1690s, though the exact signification remains uncertain despite much speculation. The measuring tool called a T-square (sometimes suggested as the source of this) is recorded by that name only from 1785.

In medicine, the T-cell (1970) is so called because the cells are derived from the thymus. As a medieval numeral, T represented 160.
