Les condicions laborals són clares.

Les is the feminine plural definite article in Catalan, equivalent to the in English.

Here, condicions is:

• feminine
• plural

So it needs les:

• la condició = the condition
• les condicions = the conditions

The noun is condició in the singular and condicions in the plural.

A very common Catalan pattern is:

• singular ending in -ió
• plural ending in -ions

For example:

• nació → nacions
• opinió → opinions
• condició → condicions

So condicions is just the regular plural form of condició.

In Catalan, adjectives often come after the noun, much more regularly than in English.

So:

• condicions laborals = working/labor conditions

This word order is normal and expected in Catalan.
Putting the adjective before the noun is usually either:

• not natural here, or
• more literary/stylistic, or
• changes the nuance

So les condicions laborals is the standard order.

Because it agrees with condicions, which is plural.

In Catalan, adjectives must agree with the noun in:

• gender
• number

Since condicions is feminine plural, the adjective must also be plural:

• laboral = singular
• laborals = plural

So:

• la condició laboral
• les condicions laborals

Because the subject is plural.

The subject is les condicions laborals = the working conditions, which is plural, so the verb must also be plural.

The verb ser works like this:

• és = is
• són = are

So:

• La condició laboral és clara.
• Les condicions laborals són clares.

Són is the 3rd person plural of ser: they are.

The accent mark helps show the correct stress and also distinguishes it from other forms or words. In practice, you should simply learn són as the standard written form meaning are.

So in this sentence:

• són = are

Because clares agrees with condicions, which is feminine plural.

The adjective clar changes like this:

• clar = masculine singular
• clara = feminine singular
• clars = masculine plural
• clares = feminine plural

So:

• La condició és clara.
• Les condicions són clares.

This is a very important pattern in Catalan: adjectives usually match the noun they describe.

Sometimes yes, but the meaning or tone can shift slightly.

In this sentence, són clares is the most neutral way to say that the working conditions are clear as a description of what they are like.

Estan clares can sound more like:

• they have become clear
• they are clear now
• the situation is clear

So:

• són clares = they are clear, as a general description
• estan clares = they are clear now / they have ended up being clear

For a basic descriptive sentence, són clares is the safest choice.

They are similar, but not always identical in style.

• condicions laborals = labor/working conditions
• condicions de treball = work conditions / conditions of work

Both are common and natural.
Condicions laborals is slightly more formal or institutional in tone, while condicions de treball can sound a bit more direct and everyday.

In many contexts, they can be used almost interchangeably.

It would be:

La condició laboral és clara.

Here is the comparison:

• les → feminine plural article
• la → feminine singular article
• condicions → plural
• condició → singular
• són → plural verb
• és → singular verb
• clares → feminine plural adjective
• clara → feminine singular adjective

So the whole sentence changes to keep agreement throughout.

A simple approximation is:

les con-di-si-ONS la-bo-RALS son CLA-res

A few useful notes:

• c before i in condicions sounds like s
• the final -s in plurals is usually pronounced
• ll does not appear here, so there is no special ll sound to worry about in this sentence
• són is stressed on the only syllable

A more careful pronunciation will vary by dialect, but this approximation is a good start.

The structure is:

Article + noun + adjective + verb + adjective

More specifically:

• Les = the
• condicions = conditions
• laborals = labor/working
• són = are
• clares = clear

So the grammar is:

Subject + verb + complement

with the subject being:

• Les condicions laborals

and the description after the verb being:

• clares

This is a very common and useful Catalan sentence pattern.
