What does deflectable mean?
'Deflectable' is an adjective describing something that can be deflected — turned aside or diverted from a straight or intended path. The word is built transparently from the verb 'deflect' plus the productive suffix '-able', which marks capability, so it literally means 'able to be turned away'. In practice it shows up most often in technical writing about physical objects and forces: deflectable surfaces, shields, fins, or particles whose trajectories can be altered by external influences such as magnetic fields or impact. It also appears figuratively, as when criticism or a difficult question is described as deflectable, meaning it can be parried or redirected rather than absorbed head-on. Because it is comparatively rare, the adjective tends to lend a precise, technical tone to whatever it modifies. Readers who know 'reflect', 'inflect', and 'deflection' will recognise the shared root immediately: all descend from the Latin verb 'flectere', meaning to bend.

Etymology of deflectable
'Deflectable' is formed from the verb 'deflect' combined with the suffix '-able'. The verb itself derives from the Latin 'deflectere', meaning to bend down or turn aside, which joins the prefix 'de-' (down, away) with 'flectere' (to bend). English adopted 'deflect' around the early 17th century, and the adjective 'deflectable' was created later by straightforward derivation. The same Latin root gives English 'reflect', 'inflect', 'flexible', and 'deflection', making the family easy for readers to recognise.
How deflectable is actually used
'Deflectable' is a relatively rare, technical-sounding adjective formed transparently from the verb 'deflect' plus the suffix '-able'. It appears most often in engineering, physics, and sports-equipment contexts, and only occasionally in figurative use. It carries no strong connotation of formality or informality, but its rarity means it may read as jargon in general prose.
