Morphology

treachery = treacherous (semi-transparent) = treach + ery

The noun is clearly related to the adjective 'treacherous' and denotes the quality/act of betrayal, but the underlying root 'treach' is not a standalone modern English word, so segmentation is not fully transparent to learners.

Etymology

Treachery comes from an old word for 'trick' or 'cheat' and is related to the familiar word trick. So treachery is about betraying someone's trust by deceiving or tricking them.
