Grammar & Word origin

Grammar:

As a noun, it is always feminine (une seconde, la seconde).
As an adjective, it is the feminine version of second . While deuxième is often used as a synonym, purists sometimes suggest using second when the sequence only has two items and deuxième when there are more than two, though this distinction is not strictly followed in modern French.

Word Origin: The word is derived from the Latin secunda, which is short for pars minuta secunda (the second small part). This historical phrase referred to the second division of the hour, with the first division being the minute .
