Primer Condicional con 'Can' (Posibilidad y Permiso Futuro)
ability o permission en posibilidades futuras y reales. ¡Es muy útil!
Grammar Rule in 30 Seconds
Use 'If + Present Simple' and 'Can + Verb' to talk about future things that are possible or allowed.
- The 'if' part uses Present Simple: 'If it rains...'
- The result part uses 'can' + base verb: '...we can stay home.'
- Use 'can' instead of 'will' to show ability or permission, not just certainty.

Puedes ir a la fiesta(la luz verde que has estado esperando).

can es tu herramienta ideal para hablar sobre consecuencias de la vida real que involucran permiso, oportunidad o habilidad. A diferencia de la versión estándar con will, que se siente como una certeza científica o una promesa sólida, la versión con can es mucho más flexible.elige tu propia aventura. Solo no lo uses para decirle a tu gato qué hacer; ignorará la condición y el resultado de todos modos.
Formation Pattern
if): Usa if seguido del Presente Simple. Aunque estemos hablando del futuro, mantenemos el verbo en presente.
can): Usa can seguido de la Forma Base del verbo (sin to, sin -ing, sin -ed).
If + [Sujeto] + [Verbo en Presente Simple], [Sujeto] + can + [Verbo Base].
If you pass the test, you can borrow my car. (Si pasas el examen, puedes tomar prestado mi coche).
can va primero, no necesitas coma.
can borrow my car if you pass the test. (Puedes tomar prestado mi coche si pasas el examen).
if comienza la oración, necesitas el bache. Si if está en el medio, actúa como el pegamento, por lo que no se necesita el bache. Es una regla simple, pero olvida la coma y un profesor de gramática en algún lugar podría perder sus alas.

Smart Tips
Just use 'can'. It's shorter, more natural, and means the same thing in a first conditional.
Use 'can' to show that the result is an option, not a requirement.
Stop! Check if the 'will' is right after 'if'. If it is, delete it.
Start the sentence with 'Can I...' to make it a question.
Pronunciación
The Weak 'Can'
In affirmative sentences, 'can' is usually unstressed and sounds like /kən/.
The Strong 'Can't'
In negative sentences, 'can't' is stressed and the vowel is clearer /kænt/ (US) or /kɑːnt/ (UK).
Rising-Falling
If it rains (rising), we can stay home (falling).
The rising tone on the if-clause shows the condition is pending; the falling tone on the result shows the conclusion.

Preguntas frecuentes (8)
Yes, but it changes the meaning. `Can` is for real/likely situations (First Conditional). `Could` is for imaginary/unlikely situations (Second Conditional).
Usually 'If I'. For example: 'If I go, I can buy it.' If you say 'If I can go', you are saying 'If I have the ability to go'.
In English, you cannot put two modal verbs together. You must use `can` alone or the phrase `will be able to`.
Only if the `if` clause comes first. 'If it rains, we can stay.' (Comma) vs 'We can stay if it rains.' (No comma).
Yes, `may` is more formal than `can` but follows the same rule: 'If it rains, we may stay home.'
It's for the future and for general truths/rules. 'If you have a ticket, you can enter' is a general rule.
The negative is `cannot` or `can't`. Example: 'If you don't pay, you can't stay.'
Yes! 'Can we go if I finish my work?' is a very common way to ask for permission.
