Questions & Answers about קח את התרופה הזאת אחרי הארוחה, ואל תשכח לשתות מים.
קח is the masculine singular imperative form of לקחת (to take). It is used when speaking to one male.
- to one male: קח
- to one female: קחי
- to a group: קחו
So this sentence is directed to a male singular listener.
In Hebrew, את marks a definite direct object. It does not mean anything by itself in English, but it tells you that the noun after it is the specific thing being acted on.
Here, התרופה הזאת means this medicine, which is definite, so Hebrew uses את:
- קח את התרופה הזאת = Take this medicine
Because את is normally used only before a definite direct object. In this sentence, מים means water in a general, non-specific sense, so את is not used.
Compare:
- לשתות מים = to drink water
- לשתות את המים = to drink the water / to drink that specific water
