Is 'to smoke' a complement or adjunct in this sentence?
I hope you are all well.
He stopped to smoke.
Is to smoke a complement of stop or is it an infinitive-of-purpose adjunct?
In a comment, John Lawler wrote:
To smoke is a purpose infinitive. Stop, unlike start, can take only gerund complements (He stopped smoking, he started smoking, he started to smoke), so any infinitive following it has to be an adjunct.
