Metonymy & antinomy – words

I learned two words today.

Metonymy is a literary device.

It is a figure of speech that replaces the name of a thing with the name of something else with which it is closely associated.

Antinomy \an-ˈti-nə-mē\

1:  a contradiction between two apparently equally valid principles or between inferences correctly drawn from such principles

2:  a fundamental and apparently unresolvable conflict or contradiction
For example, it is hard to resolve the concept of ‘election’ (from Reformed theology that some are predestined to be saved and some are not) and ‘Christ died, that all who believe will be saved.’
*Not to be confused with ‘antimony,’ which is a brittle silvery-white metalloid.
