Questions & Answers about Inumin mo ang gatas bago matulog.
Because inumin puts the focus on the thing being drunk, namely ang gatas.
A very common contrast is:
- Uminom ka ng gatas. = Drink milk / Drink some milk.
- Inumin mo ang gatas. = Drink the milk.
So:
- uminom is more actor-focus: the action of the person drinking is highlighted.
- inumin is more object-focus: the thing being drunk is highlighted.
In this sentence, the speaker is telling someone to drink a specific thing, the milk, so inumin is natural.
Inumin comes from the root inom, meaning drink.
Here, -in- and -in / -hin are part of the verb formation that creates an object-focus verb. In this sentence, inumin means something like:
- drink it
- consume it by drinking
Because the object is stated right after it, the full meaning becomes:
- Drink the milk
Also, inumin can be an imperative form, so it sounds like a command or instruction.
