Questions & Answers about De arts onderzoekt zijn bloed.

How would I add namelijk to this sentence to show it is a reason for a previous statement?
You place the explanatory adverb namelijk in the middle field, right after the finite verb. The sentence becomes: De arts onderzoekt namelijk zijn bloed. You would use this to explain a preceding sentence, for example: Hij blijft in het ziekenhuis. De arts onderzoekt namelijk zijn bloed. (He is staying in the hospital. The doctor is examining his blood, you see.)
Is onderzoeken a separable verb?
No, onderzoeken is inseparable. Even though onder can be a preposition, in this verb the stress falls on the second part (onderZOEken). Because it is inseparable, the prefix stays attached to the verb in the present tense: De arts onderzoekt.
Is there a difference between de arts and de dokter?
Both mean doctor and are often used interchangeably. Arts is slightly more formal and is used for the official profession or in specific titles (like huisarts for general practitioner or tandarts for dentist). Dokter is the common, everyday word you use, especially when addressing the doctor directly.
Can onderzoeken also mean to do research?
Yes! Depending on the context, onderzoeken can mean to examine medically, to investigate a crime, or to conduct scientific research. The related noun is het onderzoek (the investigation or the research).
