In a way that is forced, compelled, or done under pressure rather than willingly.
From 'enforced' (past participle of 'enforce') plus the adverb suffix '-ly.' It describes the manner in which something is done when force is applied.
This word is awkward to say and rarely used in modern English, but it perfectly captures that bitter feeling of doing something against your will. A smile can be 'enforcedly' given—like when you're forced to smile for a family photo.
