El veterinari llegeix el microxip durant la revisió veterinària.

Catalan often uses the definite article more than English does. So el veterinari means the veterinarian.

In a full sentence like this, using the article sounds natural because we are referring to a specific person involved in the situation. Leaving it out would usually sound incomplete unless it were a label, heading, or part of a special style.

• el veterinari = the male veterinarian
• la veterinària = the female veterinarian

This is the masculine/feminine pattern of the noun and adjective veterinari / veterinària.

• veterinari = masculine singular
• veterinària = feminine singular

So in this sentence:

• El veterinari = the male veterinarian
• la revisió veterinària = the veterinary check-up / veterinary examination

In the second case, veterinària is feminine because it agrees with revisió, which is a feminine noun.

Llegeix is the 3rd person singular present tense of llegir, meaning to read.

So:

• jo llegeixo = I read
• tu llegeixes = you read
• ell/ella llegeix = he/she reads

In the sentence, El veterinari llegeix el microxip means The veterinarian reads the microchip.

This is one of the trickier words for English speakers.

A rough guide is: lyeh-JAYSH or lleh-JAYSH, depending on accent.

A few helpful points:

• The ll in many varieties of Catalan is like a palatal sound, somewhat similar to lli in some pronunciations of Spanish ll, though pronunciation varies by region.
• The ending -eix is common in Catalan verbs and often sounds roughly like -aysh.

You do not pronounce it like English leg-eeks or lee-geeks.

Yes. Microxip is the standard Catalan form of microchip.

Catalan often adapts borrowed words to its own spelling conventions:

• English chip
• Catalan xip

In Catalan, x often represents a sh-like sound, so xip sounds close to English chip/ship depending on the word and dialect, but here it corresponds to the adapted form used in Catalan.

So:

• el microxip = the microchip

Durant means during, and it is the natural choice here:

• durant la revisió veterinària = during the veterinary check-up

It expresses that something happens in the course of that event.

Using en or a would not mean the same thing here:

• en often means in
• a often means to / at

So if you want during, durant is the right preposition.

These mean different things.

• la revisió veterinària = the veterinary check-up / the veterinary examination
  
  • Here, veterinària is an adjective describing the type of examination.
• la revisió del veterinari = the veterinarian’s examination / the check-up by the veterinarian
  
  • This stresses possession or authorship: the exam belonging to or performed by the vet.

In your sentence, revisió veterinària is the normal way to say veterinary check-up.

The accent in revisió shows the stressed syllable: re-vi-SIÓ.

Catalan uses written accents to mark stress and sometimes vowel quality. For learners, this is very helpful because the accent often tells you where to place the emphasis.

So:

• revisió → stress on the last syllable

Without the accent, the word would not follow normal spelling rules for that pronunciation.

The accent in veterinària marks the stressed syllable and helps distinguish the correct pronunciation:

• ve-te-ri-NÀ-ri-a

This accent is important because Catalan spelling uses accents systematically. For learners, it is a cue that the stress does not fall where it might by default.

Yes. This is a very normal Catalan sentence order:

• El veterinari = subject
• llegeix = verb
• el microxip = direct object
• durant la revisió veterinària = time/context phrase

So it follows a standard Subject + Verb + Object pattern, just like English:

• The veterinarian reads the microchip during the veterinary check-up.

Catalan can sometimes move elements around for emphasis, but this sentence is neutral and straightforward.

Yes, Catalan often allows subject omission because the verb ending already shows the person.

So you could say:

• Llegeix el microxip durant la revisió veterinària.

That can mean He/She reads the microchip during the veterinary check-up, depending on context.

However, keeping El veterinari makes the sentence clearer and explicitly identifies the subject.

Because veterinària here does not describe the veterinarian. It describes revisió.

• revisió is feminine
• so the adjective must also be feminine: veterinària

This is a very common point for learners: adjectives agree with the noun they modify, not with another noun elsewhere in the sentence.

So:

• El veterinari = masculine noun
• la revisió veterinària = feminine noun + feminine adjective

Yes, in context that is a very natural interpretation.

Catalan uses llegir literally as to read, but with devices, labels, codes, and chips it can correspond to English read in the technical sense, which in natural English may also be expressed as scan.

So depending on context, an English translation could be:

• The veterinarian reads the microchip
• The veterinarian scans the microchip

Both can fit.

Even though it looks similar to English revision, here revisió means something more like:

• check-up
• inspection
• examination

In veterinary or medical contexts, revisió often means a routine examination or follow-up check.

So la revisió veterinària is not veterinary revision in the English sense. It means the veterinary check-up/examination.

It can be both.

As a noun:

• el veterinari = the veterinarian

As an adjective:

• clínica veterinària = veterinary clinic
• assistència veterinària = veterinary care

In your sentence, you actually see both uses:

• veterinari = noun
• veterinària = adjective

That is a useful pattern to notice.
