semula
"Semula" means "again" or "anew" in English.
In this sentence, "semula" is used with the prefix "mem-" as part of the verb "membina" (to build) and adds the meaning of "re-" indicating the action is to be repeated, reconstructed, or done again.
Kita perlu membina semula rumah itu selepas banjir.
We need to rebuild the house after the flood.
Here, "semula" works with the verb "baca" (to read) to imply reading again, thus emphasizing the repetitive nature of the action.
Silakan baca semula surat ini.
Please reread this letter.
"Semula" modifies the verb "dikemas" (to pack) in this passive sentence to mean packing is to be done a second time, indicating repetition or adjustment.
