Attached to, connected with, or adjoining something; made to approach or attach to.
From Latin 'adfectus,' past participle of 'adficere,' meaning 'to attach to' or 'to cause to approach,' from 'ad-' (to) plus 'facere' (to make or do). The word is archaic in modern English.
The prefix 'ad-' literally means 'to' or 'toward,' which is why you see it in words like 'address,' 'adjoin,' and 'adfected'—they all carry the sense of moving something toward something else.
