deflectionn.

/dɪˈflɛkʃən/

Forms: 1600s– deflection, 1600s– deflexion.

Etymology: < Latin dēflexiōn-em, noun of action < dēflectĕre (participial stem dēflex- ) to deflect adj. Compare modern French déflexion (Dict. Acad. 1762, occurring also in 16th cent. as déflection). The non-etymological spelling deflection, now very common, is taken from the present-stem deflect-, associated with nouns of action < Latin participial stem in -ect-, as collection, dissection, etc.

1. The action of bending down; the condition of being bent or curved; also, a bend or curve (as a result).In Mechanics. The bending of any body under a transverse strain; the amount of this. In Entomology. The state of being bent downward, as the deflection of the wings when folded; also, a deflected part or margin.
