Questions & Answers about Pompa de aer protejează echilibrul biologic.

Why is it pompa and not pompă?

Because pompa is the definite form of pompă.

• pompă = a pump
• pompa = the pump

Romanian usually puts the definite article at the end of the noun instead of using a separate word like English the. So here pompa de aer means the air pump.

What does de aer mean here?

Literally, de aer means of air, but in this sentence it works like an English noun modifier and means air in air pump.

So:

• pompa de aer = the air pump

This is a very common Romanian pattern:

• mașină de spălat = washing machine
• sticlă de apă = bottle of water
• pompă de aer = air pump

So you should not translate it too mechanically as pump of air in normal English, even though that is the literal structure.

Why isn’t it pompa de aerul?

Because after de in this kind of phrase, the second noun usually stays indefinite.

Here, aer is not referring to some specific air; it is just identifying the type or function of the pump. So:

• pompa de aer = the air pump
• not pompa de aerul

Using aerul would suggest the air as a specific, already-known thing, which is not the idea here.
