Coechipierul trage o carte de joc.

Because -ul is the definite article for a masculine singular noun in Romanian.

• coechipier = teammate / fellow player
• coechipierul = the teammate

Romanian usually adds the to the end of the noun instead of putting a separate word before it, unlike English.

Trage is the 3rd person singular present tense of the verb a trage.

In this sentence, it means something like:

• draws
• takes
• sometimes more literally pulls

So Coechipierul trage o carte de joc means the teammate is drawing a playing card.

This is a good example of how Romanian verbs can have a broader range of meanings depending on context.

Here, o is the indefinite article meaning a / an for a feminine singular noun.

• carte = book or card, depending on context
• o carte = a card / a book

In this sentence, because of de joc, it clearly means a playing card, not a book.

So:

• o carte = a card
• cartea = the card

De joc means for play / for gaming, and together carte de joc means playing card.

Breakdown:

• carte = card
• joc = game
• de = of / for

Romanian often uses structures like noun + de + noun where English might use an adjective:

• carte de joc = playing card
• literally something like card for play/game

Yes. Carte can mean both book and card, depending on context.

For example:

• o carte interesantă = an interesting book
• o carte de joc = a playing card

So the phrase after it often tells you which meaning is intended.

This is the most neutral word order: subject + verb + object.

Romanian word order is somewhat flexible, so other versions are possible, but they may change the emphasis:

• Coechipierul trage o carte de joc. = neutral
• O carte de joc trage coechipierul. = marked/emphatic, not the normal choice here
• Trage coechipierul o carte de joc? = can sound like a question depending on intonation

So for a learner, the given order is the safest and most natural one.

Because pe is usually used before a direct object when it is:

• a person
• or a specific/definite animate being

Here, o carte de joc is an inanimate object and indefinite, so no pe is needed.

Compare:

• Văd coechipierul. = I see the teammate.
• Îl văd pe coechipier. = I see the teammate.
• Trage o carte. = He/She draws a card.

So in this sentence, leaving out pe is completely normal.

The ending and the verb both show that it is singular.

• coechipierul = the teammate (singular)
• trage = he/she draws (singular)

The plural would be different:

• coechipierii = the teammates
• trag = draw

So:

• Coechipierul trage... = The teammate draws...
• Coechipierii trag... = The teammates draw...

Yes, coechipier is a masculine noun.

You can tell from forms like:

• un coechipier = a teammate
• coechipierul = the teammate

If you were referring specifically to a female teammate, you would more naturally use coechipieră in many contexts:

• o coechipieră
• coechipiera

But in some real-life usage, speakers may vary depending on style and preference.

A rough English-friendly pronunciation would be:

ko-e-ki-pye-rul TRA-je o KAR-te de jok

A few notes:

• co-e is pronounced in separate syllables
• ch before i/e sounds like k
• g in joc is a hard g, like in go
• ge / gi can sound like the j in job, but here the j sound is in trage
• trage sounds roughly like TRA-je

Romanian pronunciation is fairly consistent once you learn the spelling patterns.

Yes, depending on context.

If you are talking about cards, a trage is natural and common for drawing a card. But you may also hear verbs such as:

• a lua = to take
• a extrage = to extract / draw, often more formal or specific

So:

• Coechipierul trage o carte de joc. = natural in a game context
• Coechipierul ia o carte de joc. = the teammate takes a playing card
• Coechipierul extrage o carte de joc. = more formal, like drawing from a set or deck

In everyday game language, trage is a very normal choice.
