Quan hi ha sorra al balcó, l'escombra és millor que l'aspiradora.

Hi ha is the standard Catalan way to say there is or there are.

• ha comes from the verb haver
• hi is a little locative particle that is part of this expression

So hi ha sorra means there is sand / there’s sand.

For learners, it is best to treat hi ha as a fixed expression. Even though hi originally has a meaning like there, in modern Catalan hi ha is simply the normal existential form.

Because sorra is being used as an uncountable or mass noun, like sand in English.

Catalan often leaves out the article with mass nouns in this kind of statement:

• Hi ha sorra = There is sand
• Hi ha aigua = There is water

If you said la sorra, it would sound more like the sand, referring to specific sand already identified in the context.

So in this sentence, no article is natural because it just means that sand is present on the balcony.

Al is a contraction of a + el.

• a = to / at / on / in depending on context
• el = the
• al = a + el

So:

• al balcó = on the balcony / at the balcony

In this sentence, English uses on the balcony, but Catalan uses a with places in ways that do not always match English exactly word for word.

Because in Catalan, the singular definite articles el and la usually become l' before a vowel or silent h.

So:

• la escombra → l'escombra
• la aspiradora → l'aspiradora

Both nouns are feminine, but the feminine article la is shortened before the vowel.

This is very similar to how some languages avoid vowel clash. It makes pronunciation smoother.

És millor que means is better than.

The pattern is:

• X és millor que Y = X is better than Y

So here:

• l'escombra és millor que l'aspiradora
• the broom is better than the vacuum cleaner

A key point: millor already means better, so you do not add més before it in normal standard usage here.

So:

• millor que = better than
• més millor que = incorrect

It can feel like either in English, depending on context.

In this sentence, Quan hi ha sorra al balcó... is making a general statement, so in natural English it often feels like:

• When there is sand on the balcony...
• or Whenever there is sand on the balcony...

So quan can introduce a specific time, but it can also introduce a repeated or general situation, as it does here.

Because the sentence begins with a subordinate clause:

• Quan hi ha sorra al balcó = dependent clause
• l'escombra és millor que l'aspiradora = main clause

In Catalan, when this kind of time clause comes first, a comma is very commonly used:

• Quan..., ...

It works much like English:

• When there is sand on the balcony, the broom is better than the vacuum cleaner.

So the comma helps separate the introductory clause from the main statement.

Because the subject of the main clause is l'escombra, which is singular.

The structure is:

• l'escombra = subject
• és = is
• millor que l'aspiradora = complement of comparison

So the sentence is literally:

• The broom is better than the vacuum cleaner

Even though two objects are being compared, the grammatical subject is only the broom, so the verb stays singular.

No. Millor does not agree like a regular adjective such as bo / bona / bons / bones.

It stays the same:

• el llibre és millor = the book is better
• la pel·lícula és millor = the film is better
• les escombres són millors = the brooms are better

So in the singular, you use millor for both masculine and feminine.
In the plural, it becomes millors.

Here it is singular because l'escombra is singular.

Because the sentence is talking about the two tools in a general, category-like way:

• the broom
• the vacuum cleaner

Catalan often uses the definite article for this kind of generic comparison, just as English often can:

• The broom is better than the vacuum cleaner

If you used una escombra and una aspiradora, it would sound more like comparing one unspecified broom and one unspecified vacuum cleaner in a more concrete situation.

So the definite article here is natural for a general statement about which tool is preferable in that situation.

They help show pronunciation and, in some cases, distinguish words.

• és has an accent to distinguish it from es

  • és = is
  • es = a pronoun used in reflexive constructions

• balcó has an accent because the stress falls on the final syllable:

  • bal-CÓ

So the accents are important both for reading and for telling words apart.
