Clienta îl reziliază azi.

Because -a here is the definite article attached to the noun.

• clientă = a female client
• clienta = the female client

Romanian usually puts the definite article at the end of the noun, unlike English, which uses a separate word like the.

Yes. clienta is feminine singular, so it means the female client / the woman customer.

The masculine form would be:

• clientul = the male client / the male customer

So the sentence tells you the subject is female.

îl is a direct object clitic pronoun. In this sentence, it means him or, more likely here, it, depending on what noun it refers to in the larger context.

So îl reziliază means something like:

• terminates it
• cancels it
• rescinds it

Romanian often uses these short object pronouns where English may simply say the object noun or leave it understood from context.

Because it refers to a masculine singular noun.

For example, if the thing being terminated is:

• contractul = the contract
• abonamentul = the subscription

then Romanian uses îl.

If the object were feminine singular, Romanian would use o instead.

So the pronoun agrees with the grammatical gender of the noun it replaces, not with natural gender.

Because in Romanian, these short object pronouns normally go before the conjugated verb.

So:

• îl reziliază = she terminates it

This is normal Romanian word order for clitic pronouns in a sentence like this.

reziliază is the 3rd person singular present tense of the verb a rezilia.

That means it can mean:

• he terminates
• she terminates
• it terminates

In this sentence, because the subject is clienta, it means she terminates.

It is a real and useful verb, but it sounds fairly formal and is often used in legal, business, or contract-related contexts.

It is commonly used for things like:

• contracts
• subscriptions
• agreements
• leases

So it is closer to to terminate, to rescind, or to cancel formally than to casual English cancel.

For a more general everyday idea of cancel, Romanian often uses a anula.

azi means today.

Yes, you can also say astăzi. Both are correct and common.

Very roughly:

• azi = shorter, everyday
• astăzi = slightly fuller/formal sounding in some contexts

In most situations, they are interchangeable.

Because Romanian often drops subject pronouns when the subject is already clear.

Here, the subject is explicitly given as clienta, so adding ea would usually be unnecessary.

Romanian does this much more than English does.

Yes, Romanian word order is fairly flexible.

The sentence Clienta îl reziliază azi is a normal, neutral order.

But you could also say:

• Azi clienta îl reziliază — emphasizes today
• Clienta azi îl reziliază — also possible, depending on emphasis

The exact meaning stays similar, but the focus or emphasis changes.

Grammatically, yes: îl can mean him.
But with a rezilia, the object is usually not a person. It is usually something formal like a contract or subscription.

So in real usage, îl here most likely means it, referring to some masculine noun already known from context.

Yes, grammatically it is complete. But semantically, îl points to something already known, so in real conversation it usually depends on context.

For example, earlier context might mention:

• contractul
• abonamentul
• acordul

Then îl means that thing.

So the sentence is complete, but it assumes the listener already knows what is being terminated.
