Surface Forms

Morphology

fifth + columnist

The meaning 'a secret supporter of an enemy' cannot be derived from 'fifth' (ordinal number) and 'columnist' (a writer of newspaper columns); a B1 learner would likely interpret it as a numerical label for a journalist. The term is an idiomatic/historical metaphor (from 'fifth column') whose sense is language-specific and unpredictable from its parts, so learners who know the constituents would not reliably infer the intended meaning.

Etymology

Fifth columnist comes from a 1930s war story: people said four army columns attacked a city while a secret fifth column of helpers stayed inside to help the attackers. So a fifth columnist today is someone who 'secretly helps the enemy' from within.
