inter-, intero-

(Latin: between; among, mutually, together; on the inside, internal)

Although abstracted from the many compounds in which it entered English, the form inter- was not generally considered a living prefix in English until the 1400s.

During the later period of Middle English many words borrowed in the Old and Middle French forms entre-, enter- began to be consciously respelled with Latin inter-; although vestiges of the older French borrowings are found in entertain and enterprise.

The living prefix inter- is now freely added to almost any element in English to create such formations with the meaning of "between" and "among". The words formed by intra- are closely related to this inter- prefix; in fact, they both apparently came from the same Latin source.

Etymology: "legal claim or right; concern; benefit, advantage"; earlier interesse (late 14th century), from Anglo-French interesse, "what one has a legal concern in", from Middle Latin interesse, "compensation for loss", from Latin interresse, "to concern, to make a difference, to be of importance"; literally, "to be between", from inter-, "between" + esse. "to be".

The form was influenced in the 15th century by Old French interest, "damage"; from Latin interest, "it is of importance, it makes a difference", the third person singular present tense of interresse.

The financial sense of "money paid for the use of money lent" (1520's) earlier was distinguished from usury (illegal under Church law) by being a reference to "compensation that is due from a defaulting debtor".
