El candidat tampoc està disponible.

Tampoc is the negative partner of també.

• també = also / too
• tampoc = also not / not ... either / neither

So this sentence normally connects to an earlier negative idea. For example:

• La directora no està disponible. El candidat tampoc està disponible.

That means the candidate is unavailable as well.

Catalan usually uses estar for a state or condition like availability.

So:

• està disponible = is available / is available at the moment

This sounds natural because availability is treated as a temporary state, not as an essential characteristic.

Using ser here would sound unusual in normal everyday Catalan.

Because tampoc is already a negative word.

In Catalan, when a negative word such as tampoc comes before the verb, no is often omitted:

• El candidat tampoc està disponible.

You may also come across:

• El candidat tampoc no està disponible.

Both can occur, but the version without no is very common and natural.

Also, tampoc usually makes most sense when there is a previous negative statement in the context.

El candidat is:

• el = the masculine singular definite article
• candidat = candidate

So it means the candidate.

The noun is masculine singular here. The feminine form would be la candidata.

Because disponible is an adjective that has the same singular form for masculine and feminine.

So you get:

• el candidat disponible
• la candidata disponible

Only the plural changes:

• els candidats disponibles
• les candidates disponibles

This is very common with adjectives ending in -ble.

Normally, no.

If you want to say also not / not ... either, Catalan normally uses tampoc, not també no.

So the natural sentence is:

• El candidat tampoc està disponible.

Not:

• El candidat també no està disponible.

That would sound unnatural to most speakers.

Yes. This is a very normal, neutral order:

• El candidat
  • tampoc
    • està
      • disponible

Catalan often places adverbs like tampoc before the verb, after the subject.

Other word orders are possible for emphasis, but this version is the straightforward everyday one.

Not necessarily.

Candidat can mean a candidate in different contexts, depending on the situation:

• an election candidate
• a job candidate
• an applicant
• someone being considered for something

The exact meaning comes from context.

You would change the article, the noun, and sometimes the verb/adjective agreement.

Examples:

• La candidata tampoc està disponible.
• Els candidats tampoc estan disponibles.
• Les candidates tampoc estan disponibles.

What changes:

• el / la / els / les = article
• candidat / candidata / candidats / candidates = noun
• està / estan = verb
• disponible / disponibles = adjective

The accent in està shows that the stress falls on the last syllable:

• es-TÀ

It is also simply the correct written form of the he/she/it form of estar in the present tense:

• jo estic
• tu estàs
• ell/ella està

So in this sentence, està agrees with the singular subject el candidat.
