✕Common Mistakes

Mire is the formal imperative; using it with a friend sounds overly stiff.

Aguanta should agree with the subject; if the subject is plural (las cajas), use aguantan.
Mira si la caja aguanta el peso de 20 kilos.
If you refer to a specific weight, you can say ‘el peso de X kilos’. Leaving it generic is fine, but avoid saying ‘el peso’ when the weight is already known.

Cultural Tip
In Spanish‑speaking countries, it is common to use the informal imperative (mira, comprueba) with friends, family, or coworkers you know well. In a formal setting, you would replace it with the polite form: «Mire si la caja aguanta el peso». Also, the verb aguantar can be used figuratively to mean ‘to tolerate’, so context is key.
