can

• Verbo modal que expressa capacidade, possibilidade, permissão ou pedido educado; ligado à forma do passado/condicional 'could'.

Core modal auxiliary verb expressing ability, possibility, permission, or polite request. Forms a paradigmatic pair with 'could' (past tense / conditional form). 'Could' extends 'can' to past ability, hypothetical situations, and more tentative/polite requests. Used across all English varieties without significant regional variation.

1. Present Ability or CapabilityA1formal

   Expresses that the subject possesses the physical, mental, or learned skill to perform an action in the present or as a general truth. This is the most fundamental use of 'can', indicating inherent or acquired capacity. Contrasts with 'could' which refers to past ability or hypothetical capacity.

   Habilidade ou capacidade no presente

   • I can swim across the lake in under 20 minutes.
   • He can solve complex equations mentally.
   • They can work remotely from anywhere in the world.

2. General or Theoretical PossibilityA2formal

   Indicates that something is possible in principle, may happen under certain conditions, or represents a logical deduction. Used for stating facts about what is potentially true or achievable, not referring to a specific instance. Related to 'could' which expresses more tentative or conditional possibility.

3. Informal PermissionA1informal

   Used to give, ask for, or deny permission in casual or informal contexts. Less formal than 'may', this usage is extremely common in everyday spoken English. 'Could' serves as a more polite or tentative alternative when requesting permission.

   Permissão informal

   • Can I use your charger for a few minutes?
   • Employees can take two 15-minute breaks during their shift.

   • You can't enter the lab without protective equipment.

4. Polite Request or OfferA1informal

   Employed to make courteous requests, offers of assistance, or suggestions in conversational English. While 'can' is acceptable, 'could' is often preferred for greater politeness or deference in formal situations. This function highlights the pragmatic flexibility of modal verbs in social interaction.

   Pedido ou oferta educada

   • Can you please send me the report by Friday?
   • Can I help you carry those groceries?
   • Can we schedule a follow-up meeting next week?
   • Can you clarify what you mean by 'urgent'?
   • Can I suggest we approach the problem from a different angle?

5. Logical Deduction (Negative)B1formal

   In negative form 'can't' or 'cannot', expresses strong disbelief or logical impossibility based on available evidence. Used to conclude that something is virtually impossible or contradicts known facts. 'Couldn't' serves the same function for past reference or more tentative deduction.
