Questions & Answers about Dada saya sakit malam ini.
Indonesian possession is usually noun + possessor, the opposite of English.
- dada = chest
- saya = I / me (and as a possessive: my)
So dada saya literally means chest I / my chest.
This pattern is very common:
- rumah saya = my house
- teman saya = my friend
- mobil saya = my car
You can also say dada aku, dada kamu, etc., following the same rule: noun + pronoun.
dada means chest in a general, non-technical way and is used for both men and women.
Some nuances:
- dada = chest (front upper body area, including where the heart is)
- payudara = breasts (more specific, anatomical / medical / formal)
- buah dada = breasts (more colloquial, can be a bit sensitive in tone)
In your sentence Dada saya sakit malam ini, listeners will understand it as my chest hurts tonight, not as a reference to breasts specifically, unless the context clearly points that way (e.g. at a breast clinic).
