Whenever you want to express a hope, wish, or desired outcome in a colloquial kinda way:
You can also use it on its own with sí or no:
✅ VERY common in CASUAL Mexican Spanish (but default, safe option is still ojalá que).
✅ Not vulgar or slangy, but VERY colloquial.
✅ Particularly common in speech, texts, forums, etc.
You know what I really, really, REALLY appreciate about this resource?
Every entry is written the way an actual researcher and an avid lover of languages and philology (or at least, linguistics) would want it done.
This is the way *I* would do this - because this addresses so many questions I would want to ask.
This is EXACTLY the type and the depth of material I personally always want to see in any language learning resource, yet so few offer it — AND manage to keep it light and engaging.
Ñoños of the world, unite!
