Questions & Answers about Si la tos és pitjor a la nit, has de tornar a l'hospital.
In Catalan, si without an accent means if.
- si = if
- sí = yes
So in this sentence, Si la tos és pitjor a la nit... means If the cough is worse at night...
The accent matters because it changes the meaning.
És is the verb to be in the he/she/it is form.
- és = is
- es = a pronoun, often like oneself / himself / herself / itself or part of a pronominal verb
So:
- la tos és pitjor = the cough is worse
The accent helps distinguish the verb from the pronoun.
Yes. Tos (cough) is a feminine noun in Catalan, so it takes la.
- la tos = the cough
This may feel unusual to an English speaker because English nouns do not have grammatical gender. In Catalan, you simply have to learn the noun together with its article.
