Fiica sa citește.

Because fiica is the definite form of the noun.

• fiică = daughter / a daughter
• fiica = the daughter

Romanian usually uses the definite form of the noun in this kind of possessive structure:

• fiica sa = his/her daughter
• cartea mea = my book
• fratele tău = your brother

So the -a at the end of fiica is the definite article attached to the noun.

sa is a possessive adjective meaning his or her here.

So fiica sa means his daughter or her daughter. Romanian often leaves that ambiguity to context.

A useful thing to notice: this possessive form agrees with the thing possessed, not with the owner.

Because fiica is feminine singular, the possessive form is sa.

Compare:

• fiul său = his/her son
• fiica sa = his/her daughter
• fiii săi = his/her sons
• fiicele sale = his/her daughters

That is the normal Romanian pattern in everyday language.

Romanian commonly puts the possessed noun first and the possessive after it:

• cartea mea = my book
• mama lui = his mother
• fiica sa = his/her daughter

So fiica sa is completely normal word order.

Romanian often drops subject pronouns when they are not needed.

The verb form citește already tells you the subject is third person singular: he/she/it reads.

So Romanian does not need to say ea (she) unless there is special emphasis or contrast.

For example:

• Fiica sa citește. = normal
• Ea citește. = She is reading / She reads
• adding ea in a full sentence usually gives extra emphasis

citește is the 3rd person singular present tense form of a citi (to read).

So it can mean:

• reads
• is reading

Romanian present tense often covers both the habitual and the ongoing meaning, and context tells you which one is intended.

The infinitive is a citi = to read.

Its present tense forms are:

• eu citesc = I read / am reading
• tu citești = you read / are reading
• el/ea citește = he/she reads / is reading
• noi citim = we read / are reading
• voi citiți = you all read / are reading
• ei/ele citesc = they read / are reading

So in your sentence, citește matches the singular subject fiica sa.

A rough English-style pronunciation is:

FEE-ee-ka sa chee-TESH-te

A few helpful points:

• fiica has two i letters, so it is pronounced in two vowel beats: FEE-ee-ka
• c before i or e usually sounds like ch
• ș sounds like sh

So citește sounds roughly like chee-TESH-te.

Yes. By itself, sa can be ambiguous in English terms.

So fiica sa can mean:

• his daughter
• her daughter

Usually the context makes it clear.

If a speaker wants to be especially clear, Romanian often uses:

• fiica lui = his daughter
• fiica ei = her daughter

These are very common in everyday speech.

Yes, but Fiica sa citește is the most neutral and straightforward order.

This is the standard subject + verb pattern.

Other orders are possible for emphasis or style, but they are less basic for a learner. If you are starting out, Fiica sa citește is the safest pattern to copy.

No. These are different words, and Romanian learners often mix them up.

• sa = his/her (possessive)
• să = a different word, often used in subjunctive constructions
• s-a = a verb-related form with a hyphen, as in s-a dus

So in Fiica sa citește, the correct form is plain sa, with no diacritic and no hyphen.
