Cu toate că rana este mică, medicul o dezinfectează.

It means although, even though, or though.

It introduces a contrast:

• Cu toate că rana este mică = Although the wound is small
• medicul o dezinfectează = the doctor disinfects it

A very common near-equivalent is deși:

• Deși rana este mică, medicul o dezinfectează.

Both are natural.

Because Romanian usually puts the definite article at the end of the noun.

So:

• rană = a wound
• rana = the wound

and:

• medic = a doctor
• medicul = the doctor

This is one of the biggest differences from English. Instead of a separate word like the, Romanian often attaches it to the noun.

The basic singular form is rană = wound.
When it becomes definite, it changes to rana = the wound.

This is normal for many feminine nouns ending in -ă:

• casă → casa
• masă → masa
• rană → rana

So in this sentence, rana refers to a specific wound already understood in context.

Because adjectives must agree with the noun in gender and number.

Here, rana is:

• feminine
• singular

So the adjective must also be feminine singular:

• mic = masculine singular
• mică = feminine singular
• mici = plural

That is why we get:

• rana este mică = the wound is small

Este is the 3rd person singular of a fi = to be.

So:

• rana este mică = the wound is small

Romanian normally uses the verb to be here, just like English does. In casual speech, you may also hear:

• rana e mică

where e is the shorter spoken form of este.

O is a direct object pronoun meaning it here.

It refers back to rana:

• rana is feminine singular
• so the pronoun is o

So:

• medicul o dezinfectează = the doctor disinfects it

This o is not the same thing as:

• o = a / one in phrases like o rană = a wound

Here it is a pronoun because it stands before the verb and replaces the noun.

Because in Romanian, unstressed object pronouns usually come before the conjugated verb.

So Romanian says:

• medicul o dezinfectează

while English says:

• the doctor disinfects it

This word order is very normal in Romanian:

• îl văd = I see him
• o cunosc = I know her
• o dezinfectează = he/she disinfects it

Yes. You could also say:

• Cu toate că rana este mică, medicul dezinfectează rana.

That is grammatical, but it sounds more repetitive. The version with o is smoother and more natural because the noun has already been mentioned.

So Romanian often does exactly what English does here:

• mention the noun once
• then use a pronoun

It is the present tense, 3rd person singular, from a dezinfecta = to disinfect.

So:

• eu dezinfectez = I disinfect
• tu dezinfectezi = you disinfect
• el/ea dezinfectează = he/she disinfects

In this sentence:

• medicul o dezinfectează = the doctor disinfects it

Depending on context, Romanian present can sometimes match either:

• disinfects
• is disinfecting

English chooses between simple and progressive more strictly than Romanian does.

Because Cu toate că rana este mică is a subordinate clause placed before the main clause.

The comma separates:

• the concessive clause: Cu toate că rana este mică
• the main clause: medicul o dezinfectează

So the structure is:

• Although the wound is small, the doctor disinfects it.

If the clauses were reversed, you would also normally separate them:

• Medicul o dezinfectează, cu toate că rana este mică.

Yes. Romanian allows some flexibility.

For example:

• Cu toate că rana este mică, medicul o dezinfectează.
• Medicul o dezinfectează, cu toate că rana este mică.

Both are correct. The original version puts more emphasis on the contrast first: although the wound is small...

Inside the main clause, however, the pronoun still normally stays before the verb:

• medicul o dezinfectează

Not necessarily formal, but it is a bit fuller and slightly more explicit. In many everyday situations, cu toate că and deși are interchangeable.

Compare:

• Cu toate că rana este mică, medicul o dezinfectează.
• Deși rana este mică, medicul o dezinfectează.

Both mean the same thing. A learner should understand and use both.

The letter ă is a very common Romanian vowel. It is a short central sound, somewhat like the a in English about, but shorter and cleaner.

So:

• că sounds roughly like kuh
• mică sounds roughly like MEE-kuh
• dezinfectează ends with -ea-zuh

You do not need a perfect English equivalent, but it is important not to pronounce ă like a full a in father. It is a weaker, central vowel.
