How to Say "once" in Spanish
The Spanish word for “once” is “cuanto” — B1 level. This is a very common word in everyday Spanish.

En cuanto lo vi, supe que algo andaba mal.

Future Actions Need a Special Verb Form
When you use 'en cuanto' to talk about something that will happen in the future, the verb that follows often changes into a special form called the subjunctive. For example, 'en cuanto llegue' (as soon as he arrives) instead of 'en cuanto llega'.
Mixing up 'en cuanto' and 'en cuanto a'
Mistake: “En cuanto el clima, prefiero el sol.”
Correction: 'En cuanto a' means 'regarding'. 'En cuanto' means 'as soon as'. The correct sentence is: 'En cuanto al clima, prefiero el sol.' (Regarding the weather, I prefer the sun).
