Build French verbs with à or de before an infinitive

J'apprends à nager, j'ai oublié de fermer, je veux partir: tap the tiles and learn which verbs need à, de, or nothing before an infinitive.

In short

Some verbs link straight to an infinitive (vouloir, pouvoir, devoir, aimer, aller: je veux partir). Others need à (apprendre à, commencer à, réussir à, aider à) or de (oublier de, essayer de, décider de, arrêter de, finir de). There's no logic you can rely on: learn them in chunks.

Which French verbs take à or de before an infinitive?

Some verbs change meaning with the preposition: commencer à and commencer par (to start by), décider de (to decide to) and se décider à (to make up one's mind to). Dictionaries show the construction: look for qqn à faire qqch or de faire qqch.
