Why is 'tengah' not acceptable here?
What is the difference between "tengah" and "pertengahan"?
Tengah itu adalah sebuah kata yang utuh, tapi pertengahan memiliki himpunan "per" dan "an"
Does anyone know why can't you use 'yang lalu' instead of just 'lalu' here? Thank you.
Yes it should be accepted too
Thank you Annita1980
Tengah is colloquially okay, but when you have an object, you can follow it with the advern which can be made by using per-an, pertengahan
