Frequently Asked Questions
So what's the deal with 'fino'?
'Fino' means 'fine,' 'delicate,' or 'thin' but for objects, not people's bodies. Think 'una línea fina' (a thin line), 'jamón fino' (finely sliced ham), or 'un vino fino' (a fine wine). It can also describe someone as 'refined' or 'elegant' in their manners, but not physically thin.
Can 'flaco' ever be positive?
Yes, but it's very dependent on region and tone. In places like Argentina and Uruguay, 'Flaco' and 'Flaca' are very common, affectionate nicknames or ways to get someone's attention, similar to 'buddy' or 'pal'. Outside of these regions, it's safer to stick to its meaning of 'skinny'.
Is 'delgado' always a compliment?
Not necessarily a compliment, but it's almost always neutral. It's a factual, respectful way to say someone is slim. It only becomes a compliment when you add context, like '¡Te ves muy delgado y saludable!' (You look so slim and healthy!).
