UBS Dictionary of the Greek New Testament
noun, f. | -εως | λύω
34.78 · Association · Marriage, Divorce
to divorce, to separate to dissolve the marriage bond Expressions for divorce are often based on terms meaning literally ‘to send away,’ ‘to separate from,’ or ‘to leave one another.’ However, in a number of languages idiomatic expressions are employed, for example ‘to send him off with his clothes,’ ‘to untie the knot between them,’ or ‘to throw away her hearthstones.’
Some persons have attempted to make an important distinction between ἀφίημι in 1CO 7:11 and χωρίζω in 1CO 7:15 on the assumption that ἀφίημι implies legal divorce, while χωρίζω only relates to separation. Such a distinction, however, seems to be quite artificial.
