Medicul verifică sângele.

Because Romanian usually puts the definite article at the end of the noun, not before it.

• medic = doctor
• medicul = the doctor

So -ul is the masculine singular definite article here. This is one of the biggest differences from English.

For the same reason: sângele is the definite form of sânge.

• sânge = blood
• sângele = the blood

Even though blood is a mass noun in English, Romanian can still use the definite article with it, especially when referring to the blood being discussed or examined in a specific situation.

Verifică is the 3rd person singular present tense of the verb a verifica, meaning to check or to examine.

So verifică can mean:

• checks
• is checking
• sometimes does check

Romanian present tense often covers both the simple present and the present progressive, depending on context.

Because Romanian normally uses an enclitic definite article, which means the article is attached to the end of the noun.

So instead of saying something like the doctor with a separate word, Romanian says medicul. Instead of the blood, it says sângele.

This is completely normal Romanian grammar.

Romanian often leaves out subject pronouns because the verb form already shows the person and number.

Here, verifică tells you the subject is he/she/it or a singular formal subject like the doctor. Since medicul is already stated, there is no need to add el or ea.

So Romanian often sounds more compact than English in this way.

Because pe is usually used before specific direct objects that are people, or sometimes highly specific animate beings.

Here, sângele is an inanimate direct object, so pe is not used.

Compare the idea:

• Medicul verifică sângele. = normal
• Medicul verifică pacientul. = this may take pe in many contexts: Medicul îl verifică pe pacient.

So the absence of pe here is expected.

Yes. Medicul verifică sângele. follows the very common subject–verb–object order:

• Medicul = subject
• verifică = verb
• sângele = object

This is the most neutral and natural order for a basic statement.

Romanian can change word order for emphasis, but this version is the standard one a learner should recognize first.

These are two important Romanian vowels:

• ă in verifică is a short, neutral sound, somewhat like the a in sofa
• â in sângele has no exact English equivalent; it is a central vowel pronounced with the tongue raised in the middle of the mouth

So these letters are not optional spelling details; they represent real sound differences.

It can mean both.

Romanian present tense does not always distinguish between:

• The doctor checks the blood
• The doctor is checking the blood

Context usually tells you which English translation is best. In an isolated learning sentence, either can be appropriate depending on the intended meaning already given to the learner.

Yes, but medic is a very standard and common word for doctor/physician in Romanian. In this sentence, medicul is a perfectly natural choice.

A learner should definitely become comfortable with medic because it appears very often in everyday Romanian.
