The story
- Latin · borrowed fromdēflexiō
- English todaydeflection
From Latin dēflexiō, from dēflectere (“to deflect”; participle stem dēflex-) + -iō (suffix forming abstract nouns). The non-etymological spelling deflection is taken from the present stem dēflect-, associated with collection, dissection, etc. By surface analysis, deflect + -ion.
