intra-
(Latin: within, inside, on the inside)
Borrowed from late Latin intra-; closely related to inter-, "between". The use of intra- is largely a product of modern times, occurring in words of common and technical vocabulary, where once it was generally a term used in science and the academic world.
While some words are borrowings from Medieval and even Late Latin, few if any come from Classical Latin.
