No tinc cap problema per cancel·lar la cita de demà.

Catalan often leaves out subject pronouns because the verb ending already shows who the subject is.

• tinc = I have
• so No tinc... already means I don’t have...

You could add jo for emphasis or contrast:

• Jo no tinc cap problema... = I don’t have any problem...

But in a neutral sentence, leaving it out is more natural.

Negation in Catalan is usually very simple:

• no + verb

So:

• No tinc = I don’t have
• No vull = I don’t want
• No puc = I can’t

Unlike English, Catalan does not need an extra helping verb like do here.

Also, tinc is the 1st person singular present of tenir = to have.

Yes, cap can be a noun meaning head, but that is not what it means here.

In this sentence, cap is a determiner meaning any or no, especially in negative contexts.

So:

• No tinc cap problema = I don’t have any problem
• or more naturally in English, I have no problem

This no + cap pattern is very common in Catalan:

• No tinc cap idea = I have no idea
• No veig cap cotxe = I don’t see any car

You may hear that sometimes, but No tinc cap problema is the more standard and complete form.

Using cap makes the negative idea clearer and more idiomatic:

• No tinc cap problema = I have no problem / I don’t have any problem

So for learners, no + cap + noun is a very good pattern to remember.

Many Catalan nouns ending in -a are feminine, but not all of them.

Problema is masculine:

• el problema
• un problema
• cap problema

This is common with some words of Greek origin, such as:

• el problema
• el tema
• el sistema

So the ending -a does not always mean feminine.

Here, per + infinitive introduces the action connected to the noun problema.

So:

• cap problema per cancel·lar la cita = no problem cancelling the appointment

English often uses with + -ing in this kind of sentence:

• I have no problem cancelling...

Catalan commonly uses per + infinitive instead.

So this is a useful pattern:

• No tinc cap problema per ajudar-te
• No tenim cap problema per esperar

That middle dot is called the punt volat.

It appears in l·l and shows that this is not the same as ll.

• ll is a different Catalan sound
• l·l means two separate l sounds, or a doubled l

So cancel·lar is not pronounced like a word with ll such as lluna.

Also, the accent mark in cancel·lar shows that the stress falls on the last syllable.

Because de demà is describing the noun cita.

• la cita de demà = tomorrow’s appointment

Here demà is part of the noun phrase.

If you said cancel·lar la cita demà, that would more likely sound like:

• to cancel the appointment tomorrow

In other words, demà would sound like it modifies the action, not the appointment itself.

So de demà is important if you mean the appointment/date that is scheduled for tomorrow.

It can mean either one.

• In an everyday practical context, it often means appointment
• In a romantic context, it can mean date

So la cita de demà could mean:

• tomorrow’s appointment
• or tomorrow’s date

The surrounding context tells you which meaning is intended.

Because the speaker is talking about their current attitude toward a future action.

Right now, they are saying they have no objection or difficulty about cancelling something that will happen tomorrow.

So the time reference works like this:

• tinc = present state or attitude now
• la cita de demà = the appointment/date is tomorrow
• cancel·lar = the action being discussed

This is normal in both Catalan and English:

• I have no problem cancelling tomorrow’s appointment

The attitude is present, even though the appointment is in the future.
