Questions & Answers about Sumur itu sangat dalam.

What does sumur mean exactly? Is it just well, or can it mean other things too?

Sumur is most commonly a water well (a hole dug in the ground to get water).
It usually refers to a man‑made well, not a natural spring or pond.
Other water sources have different words, like mata air (spring) or kolam (pond/pool), so sumur is specifically the kind of well you draw water from with a bucket or pump.

Why is there no word for is in Sumur itu sangat dalam?

In Indonesian, when you link a noun to an adjective, you usually don’t use a verb like “is/are”.
So Sumur itu sangat dalam literally feels like “That well very deep”, but it’s perfectly correct and natural.
A linking verb like adalah is mostly used before nouns or long explanations, not before adjectives like dalam.

What does itu do here? Is it that or the?
