Surface Forms

Morphology

fly + in + the + ointment

The literal image of a fly contaminating ointment provides a clear metaphorical link to something small that spoils a useful or pleasant thing, so a learner who knows the words can grasp the general negative idea. However, the idiomatic extension to 'a minor but annoying flaw in an otherwise good situation' and its conventionalized usage are not fully predictable or guaranteed to be understood without prior exposure, and similar metaphors are not uniformly present across languages.

Etymology

Fly in the ointment comes from the image of a small fly falling into a pot of ointment, a rich healing cream or perfume, and ruining it. So it now means a small problem that 'spoils' an otherwise good situation.
