dot the i's and cross the t's

Equivalents in other languages

Origin: In handwriting, it is easy to leave out the dot on an i or the cross stroke on a t, especially in joined-up script, so careful writers went back to add them. The phrase for attention to every detail is recorded from the 19th century.
