Questions & Answers about Maktaba iko mbali, lakini tutakwenda kwa miguu.
Because iko is the natural form for saying that something is in a place or is at some distance/location.
So:
- Maktaba iko mbali = The library is far away
- ni is more for identity or classification
Compare:
- Maktaba ni jengo = A library is a building
- Maktaba iko mjini = The library is in town
- Maktaba iko mbali = The library is far away
So in this sentence, iko is the better choice because the speaker is talking about the library's location/distance, not what it is.
