Ecusonul identifică colegul la stația de lucru.

Romanian usually puts the definite article at the end of the noun, not before it as English does.

So in this sentence:

• ecusonul = the badge
• colegul = the colleague
• stația = the station

A few useful comparisons:

• ecuson → ecusonul
• coleg → colegul
• stație → stația

In general, singular masculine and neuter nouns often take -ul, while singular feminine nouns often take -a.

Identifică is the 3rd person singular present form of a identifica.

So it means identifies or is identifying, depending on context.

Romanian often leaves out subject pronouns such as el or ea because the verb ending already shows the person and number. That means identifică by itself already tells you the subject is he/she/it or a singular noun such as ecusonul.

In standard Romanian, a specific human direct object is normally marked with pe. Because colegul refers to a specific person, many learners would expect:

Ecusonul identifică pe coleg la stația de lucru.

In very natural modern Romanian, many speakers would also use clitic doubling:

Ecusonul îl identifică pe coleg la stația de lucru.

So the version without pe may be understandable, especially in technical or simplified wording, but learners should know that pe is the usual marker with a definite person as the direct object.

The main clue is word order. The normal neutral order in Romanian is:

subject + verb + object

So:

• ecusonul = subject
• identifică = verb
• colegul = object

Context and real-world meaning also help. A badge identifies someone; a colleague does not normally identify a badge in this kind of sentence.

If pe were added before colegul, the object would be even clearer.

La here means at.

So la stația de lucru means at the workstation.

Literally, stația de lucru is something like the station of work, but Romanian often uses de + noun to create this kind of descriptive phrase. It works a lot like English compounds such as workstation, work table, or work schedule.

Similar patterns:

• masă de lucru = work table
• program de lucru = work schedule
• stație de lucru = workstation

Lucru stays in its basic form here because it is part of that fixed descriptive structure after de.

Yes. Colegul is grammatically masculine singular definite, so it means the male colleague or the colleague when the person is male.

For a female colleague, Romanian uses colegă in the indefinite form and colega in the definite form.

So:

• un coleg = a male colleague
• colegul = the male colleague
• o colegă = a female colleague
• colega = the female colleague

Yes, ecuson is normally treated as a neuter noun in Romanian.

Romanian neuter nouns behave:

• like masculine in the singular
• like feminine in the plural

That is why the singular definite form looks masculine:

• un ecuson
• ecusonul

And the plural behaves differently:

• două ecusoane
• ecusoanele

This masculine-in-the-singular / feminine-in-the-plural pattern is very common for Romanian neuter nouns.

Two important sounds here are:

• ă in identifică: a short neutral vowel, similar to the a in English sofa
• ț in stația: ts, like the end of English cats

A rough pronunciation guide for a few words:

• ecusonul ≈ eh-koo-SOH-nul
• identifică ≈ ee-den-tee-FEE-kuh
• colegul ≈ ko-LEH-gul
• stația ≈ STA-tsi-a

The diacritics matter in Romanian, so ă and ț should not be ignored when reading aloud.
