The present tense of cansar: full table

The gerund of cansar is cansando and the past participle is cansado. The gerund is used for the progressive (estoy cansando), and the participle is used with haber in all perfect tenses (he cansado).
How the present tense of cansar is formed
The present tense of cansar is built from the stem cans- plus the regular -ar endings: -o, -as, -a, -amos, -áis, -an. Take the infinitive, remove the -ar ending, and add the ending that matches the person: yo canso, tú cansas, él cansa, nosotros cansamos, vosotros cansáis and ellos cansan. Once you know the pattern for one regular -ar verb, you can apply it to hundreds of others.
In everyday use, cansar usually works like gustar: the thing that produces the feeling is the subject of the sentence, and you are the indirect object. So you say me cansa el ruido de la calle — literally, the thing is the subject and you are the person it affects — rather than starting with yo. The verb agrees with the thing, not with you: one thing takes the singular form cansa, and several things take the plural form cansan. The full table above still matters, because the transitive use (for example, cansar a alguien) uses the ordinary persons.
Two more forms belong with this tense. The gerund is cansando, used for the progressive with estar: estoy cansando. The past participle is cansado, used with haber in all perfect tenses: he cansado. Both forms appear constantly, so they are worth memorising on their own.
When to use the present tense with cansar
1. Noise and tiredness
Me cansa el ruido de la calle is the everyday complaint of city life. The noise is the subject, and you are the person it affects, which is why the verb is cansa and the pronoun is me. For example: Me cansa el ruido de la calle. — "The street noise tires me."
2. Long lessons and heat
Me cansan las clases largas shows the plural agreement: las clases is plural, so the verb is cansan. The same pattern works for heat, waiting and any other tiring thing. For example: Te cansan las clases largas. — "Long lessons tire you."
3. Getting tired yourself
Me canso después de correr shows the reflexive use. Here you are the subject, and the pronoun me is reflexive, not an indirect object. It means I get tired, not something tires me. For example: Le cansa el calor del verano. — "The summer heat tires him."
4. Plans and the near future
The present tense is also used for plans that are already fixed, especially with a time expression. Spanish speakers often say the present where English would use a future: the plan is so certain that it feels like a fact. For example, to talk about tomorrow's plan you can use the future — Mañana, me cansará esperar en la cola. — "Tomorrow, waiting in the queue will tire me." — but in conversation you will also hear the present used the same way.
5. General truths and routines
Finally, the present tense states general truths and routines: what usually happens, what is always true, what people normally do. It is the tense of habits and of facts that do not belong to one moment. For example: Normalmente, le cansa el ruido de la calle. — "Normally, the street noise tires him."
Present vs preterite: cansar
The closest tense to the present is the preterite, and learners mix them up constantly. The rule is simple: the present describes habits, routines and general truths, while the preterite describes one action that started and finished in the past. The three pairs below show the difference with cansar.
Pair 1
- Present (habit): Cada día, me cansa el ruido de la calle. — "Every day, the street noise tires me."
- Preterite (one finished action): Ayer, me cansó el ruido de la calle. — "Yesterday, the street noise tired me."
The first sentence describes something that happens regularly. The second describes something that happened once, yesterday, and is now finished. If you can add cada día, use the present; if you can add ayer, use the preterite.
Pair 2
- Present (habit): Cada día, me cansan las clases largas. — "Every day, long lessons tire me."
- Preterite (one finished action): Ayer, me cansaron las clases largas. — "Yesterday, long lessons tired me."
The first sentence describes something that happens regularly. The second describes something that happened once, yesterday, and is now finished. If you can add cada día, use the present; if you can add ayer, use the preterite.
Pair 3
- Present (habit): Cada día, me cansa el calor del verano. — "Every day, the summer heat tires me."
- Preterite (one finished action): Ayer, me cansó el calor del verano. — "Yesterday, the summer heat tired me."
The first sentence describes something that happens regularly. The second describes something that happened once, yesterday, and is now finished. If you can add cada día, use the present; if you can add ayer, use the preterite.

Common mistakes with cansar in the present tense
Mistake 1
- Wrong: Yo canso el ruido.
- Right: Me cansa el ruido.
- Why: When something tires you, cansar works like gustar: me cansa el ruido. Yo canso would mean I tire someone else.
Mistake 2
- Wrong: Me cansa las clases largas.
- Right: Me cansan las clases largas.
- Why: The verb agrees with the subject. Las clases is plural, so the verb must be cansan.
Mistake 3
- Wrong: Me canso el ruido.
- Right: Me cansa el ruido. / Me canso con el ruido.
- Why: Me canso means I get tired. To say the noise tires you, use me cansa el ruido. The two structures are not interchangeable.
Mistake 4
- Wrong: Ayer, me cansa el ruido de la calle.
- Right: Ayer, me cansó el ruido de la calle.
- Why: Ayer means yesterday, so the action is finished and needs the preterite. The present tense is for habits and routines, not for yesterday.
Mistake 5
- Wrong: Me cansais el ruido de la calle.
- Right: Me cansáis el ruido de la calle.
- Why: The form is cansáis, with a written accent. The accent is part of the spelling, and without it the word is misspelled.
