Morphology

deviation = deviate (semi-transparent) = deviate + ion

The noun is formed by a regular suffixation of '-ion' to the verb 'deviate', but the compass-specific technical sense is somewhat specialized vocabulary for many learners.

Etymology

Deviation comes from the Latin parts de- 'away' and via 'way'. For a compass, think of the needle being pushed 'away from its way' by nearby metal or magnets, which is why a deviation changes the compass reading.
