Common mistake
- •The typical error: "He stopped to smoke" = he stopped (what he was doing) in order to smoke (purpose: he started smoking).
- •"He stopped smoking" = he gave up smoking (the action he abandoned was smoking).
- •They are opposites: the first implies he still smokes after the pause; the second, that he no longer smokes.
Trick to remember it
- •The definitive question: is the mentioned action what STARTS happening after the pause? = STOP + TO.
- •Is the mentioned action what IS BEING ABANDONED? = STOP + -ING.
- •"He stopped TO eat" = started eating after the pause.
- •"He stopped EATING" = gave up eating (eating is what was abandoned).
Quick rule
- •STOP + TO + infinitive = pause (from whatever) in order to do the infinitive action (purpose).
- •STOP + -ING = cease the gerund action (giving it up).
- •"Stopped to eat" = paused to eat.
- •"Stopped eating" = gave up eating.
Did you know?
STOP is the most elegant example of why the gerund/infinitive distinction matters in English. "The doctor stopped to prescribe medication" and "The doctor stopped prescribing medication" have radically opposite meanings, and the only morphological difference is TO vs -ING. Corpus linguists have found that the most frequent verbs appearing with STOP + -ING in real English are: "stop working," "stop trying," "stop taking," "stop using," and "stop doing." Those appearing with STOP + TO include: "stop to think," "stop to look," "stop to consider," and "stop to check." This distribution shows that STOP TO frequently pairs with cognitive verbs (think, look, consider), while STOP -ING pairs with more concrete habits and processes.

'Start' and 'begin' accept both gerund and infinitive with no meaning difference, except with stative verbs or in continuous forms.
'Suggest' and 'recommend' never take 'to' + infinitive; they use a gerund or a 'that' clause.
