(Fuller) "By the secular cares and avocations which accompany marriage the clergy have been furnished with skill in common life."

Avocation (in the singular) for vocation is usually avoided by good writers. 3. Pursuits; duties; affairs which occupy one's time; usual employment; vocation.

The words may, however, in many cases be interchanged. "No man can pray from his heart to be kept from temptation, if the take no care of himself to avoid it." (Mason) "So Chanticleer, who never saw a fox, yet shunned him as a sailor shuns the rocks." (Dryden) Origin: OF. Esvuidier, es (L. Ex) + vuidier, voidier, to empty. See Void.
