Etymology
The word 'affect' originates from the Latin verb 'afficere', which is a compound of 'ad-' ('to') and 'facere' ('to do, make'). Its literal sense was 'to do something to, to act upon'. This meaning evolved through Old French 'affecter' into Middle English, retaining the core idea of producing an influence or change. The psychological sense of 'to touch the feelings of' developed in the 14th century, while the secondary meaning of 'to put on a pretense of' arose from the notion of assuming a manufactured or 'made' manner.
Analysis
Structure: af (towards) + fect (make, do)
