Origin

Used since at least the mid-1800s, this idiom probably began as an admonishment to school children to include the dot over their i’s and to cross their t’s when writing. It alludes to an old-fashioned style of writing where the writer completed the word in one movement of the pen and then went back to dot any i’s and add cross-strokes to any t’s to complete the letters, something that could be easily forgotten when in a hurry. During the 1800s, the idiom was more often given with the t’s first, as in cross your t’s and dot your i’s. Today, the i’s usually come first.
