Questions & Answers about Czujniki monitorują wstrząsy.
How would I use this lesson's target phrase co do to say "As for the tremors, the sensors monitor them"?
You would start with co do followed by the Genitive case. For the plural noun wstrząsy, the Genitive form is wstrząsów. You would say: Co do wstrząsów, czujniki je monitorują. Notice that you also need to add the pronoun je (them) because the verb needs a direct object.
Is the word czujniki related to the verb czuć (to feel)?
Yes! A czujnik is literally a device that "feels" or senses something. You will see this root in many related words, like czujny (watchful) and czułki (antennae). Because sensors are inanimate objects, the plural takes the standard non-masculine-personal ending -i.
Does the word wstrząsy only refer to physical tremors or earthquakes?
While here it refers to physical vibrations, wstrząs is also the standard word for medical or emotional shocks. For example, wstrząs mózgu is a concussion, wstrząs anafilaktyczny is anaphylactic shock, and a deeply distressing event can simply be called a wstrząs.
What case is wstrząsy in this sentence?
It is in the Accusative case because it is the direct object of the verb monitorują. For masculine inanimate nouns like wstrząs, the Accusative plural looks exactly the same as the Nominative plural, which is why it ends in -y here.
