¿Puedo usar su teléfono?

When to use

This is used in situations where you urgently need to make a call or send a message and do not have your own phone available or working. It should be used sparingly and with politeness.

How it works

The phrase uses the verb 'poder' (can/to be able to) in the first-person singular present indicative 'puedo' (I can), followed by the infinitive 'usar' (to use) and the possessive phrase 'su teléfono' (your phone).

• puedo: first-person singular present indicative of 'poder' (I can).
• usar: infinitive verb 'to use'.
• su teléfono: 'your phone'. 'Su' can refer to 'usted' (formal you) or 'ustedes' (plural you), or even 'él/ella/ellos/ellas' (he/she/they). Context clarifies.

Register and formality

The use of 'puedo' makes this a question about ability, which functions as a polite request. The possessive 'su' implies a degree of formality or respect, suitable for asking someone you don't know well. The informal 'tú' version would be '¿Puedo usar tu teléfono?'.

Notes

Use only when necessary and politely. Neutral everyday wording.
