Questions & Answers about Kami sangka jalan itu selamat.
Malay has two different words for we:
- kami = we, but not including the person being spoken to
- kita = we, including the person being spoken to
So Kami sangka jalan itu selamat means the speaker and some others thought so, but the listener was not part of that group.
Sangka usually means something like:
- to think
- to assume
- to suppose
- to suspect
It often suggests an assumption or belief, sometimes one that later turns out to be wrong.
So in this sentence, sangka is not just neutral thinking in every possible sense. It has more of an we assumed / we thought feeling.
Both sangka and menyangka can be used as verbs.
In everyday Malay, sangka by itself is very common and natural:
- Saya sangka...
- Kami sangka...
Menyangka is also possible, but it can sound a bit more formal or less common in ordinary conversation.
So this sentence is normal as it is.
