relate v.

late 14c., referren, "to trace back (a quality, etc., to a first cause or origin), attribute, assign," from Old French referer (14c.) and directly from Latin referre "to relate, refer," literally "to carry back," from re- "back" (see re-) + ferre "to carry, bear" (from PIE root *bher- (1) "to carry," also "to bear children").

The meaning "to commit to some authority for consideration and decision" is from mid-15c.; sense of "to direct (someone) to a book, etc." for information is from c. 1600. Related: Referred; referring.

"person devoted to religious work," especially "child dedicated by his or her parents to monastic life and raised and trained in a monastery and held in monastic discipline," 1756, from Medieval Latin oblatus, noun use of Latin oblatus, variant past participle of offerre "to offer, to bring before," from ob- (see ob-) + lātus "carried, borne," used as past participle of the irregular verb ferre "to bear."

Presumably lātus was taken (by a process linguists call suppletion) from a different, pre-Latin verb. By the same process, in English, went became the past tense of go. Latin lātus is said by Watkins to be from *tlatos, from PIE root *tele- "to bear, carry" (see extol), but de Vaan says "No good etymology available."
