This chance conversation pointed out to me the power of the suffix -aholic.
A cluster of -aholic metaphors has started to creep into our everyday language.
The tenor, or underlying ground, for all the -aholic metaphors is, of course, alcoholic.
This cluster of -aholic metaphors is but one in a series of drug-related and addiction-related metaphors that have crept into our language since the 1960s.
But the metaphor-making suffix -aholic requires one, so I felt obligated to supply one when writing about it.
Perhaps similar dynamics are at work with our other -aholics.
