When you want to connect two verbs in English, you usually place the word "to" between them. For example, you say "I want to learn" or "She likes to read". Because of this, English speakers learning French often feel tempted to insert a small preposition like à or de between verbs to translate the English "to".
However, many of the most common French verbs are followed immediately by an infinitive, with absolutely no preposition in between. If you use verbs of preference, verbs expressing ability, desire or obligation, or verbs expressing hopes and intentions, you must link the two verbs directly.

How the construction works
In French, the infinitive form of a verb (like manger, finir, or prendre) already includes the meaning of "to". Manger translates to "to eat". Therefore, you do not need an extra word for "to" when you pair it with certain conjugated verbs.
To say "I want to eat", you take the conjugated form of vouloir (I want) and place the infinitive manger (to eat) right after it.
Je veux manger une pomme.
(I want to eat an apple.)
Nous allons travailler demain.
(We are going to work tomorrow.)
Abilities, desires and obligation
The core verbs expressing ability, desire or obligation in French always take a direct infinitive. These include vouloir (to want), pouvoir (to be able to), and devoir (must or to have to). Similarly, savoir connects directly to an infinitive when expressing that you know how to do something.
Il ne peut pas venir aujourd'hui.
(He cannot come today.)
Vous devez partir maintenant.
(You have to leave now.)
Elle sait parler espagnol.
(She knows how to speak Spanish.)
Preferences, hopes, and intentions
Verbs that express your tastes and preferences also skip the preposition. This includes aimer (to like), adorer (to love), détester (to hate), and préférer (to prefer). Just attach the activity you like or dislike directly to the verb.
J'aime lire le soir.
(I like to read in the evening.)
Ils préfèrent rester à la maison.
(They prefer to stay at home.)
You follow the exact same pattern when talking about your hopes, wishes, and plans using verbs like espérer (to hope), souhaiter (to wish), compter (to plan or intend), and oser (to dare).
J'espère te voir bientôt.
(I hope to see you soon.)
Je compte voyager en France cet été.
(I intend to travel to France this summer.)
Il n'ose pas demander.
(He does not dare to ask.)
Summary
When using verbs expressing ability, desire or obligation (like vouloir and pouvoir), verbs of preference (like aimer), or verbs of intention, resist the urge to add à or de. The French infinitive already means "to do" the action, so you can connect the two verbs directly.
