Questions & Answers about Barua muhimu zimetumwa ndani ya sanduku lililofungwa vizuri.

Why does barua take the plural agreement prefix zi- in zimetumwa, even though barua looks unchanged?

barua belongs to noun class 9/10, which has identical singular and plural forms. The verb agrees in number, so zi- marks “they” (the letters) in plural. Hence zimetumwa = “they have been sent.”

What are the parts of the verb zimetumwa?

Breakdown of zimetumwa:
• zi- = class 9/10 subject prefix (“they”)
• -me- = perfect aspect marker (“have”)
• -tum- = verb root (“send”)
• -wa = passive suffix (“be sent”)
Together: “they have been sent.”

Why is the verb in passive voice here, and how would you say it in active voice?

The passive focuses on the letters as recipients of the action. An active-voice version could be:
Mtu ametuma barua muhimu ndani ya sanduku lililofungwa vizuri.
= “Someone has sent the important letters inside the well-closed box.”

Why does the adjective muhimu follow barua instead of preceding it?

Swahili uses the order Noun → Adjective. So barua muhimu literally “letters important” = “important letters.”

What does ndani ya sanduku mean, and why do we need ya?

ndani is a locative noun meaning “inside.” It requires a genitive connector: ya + noun. Thus ndani ya sanduku = “inside of the box.”

Could you use katika sanduku instead, and is there a nuance?

Yes, katika sanduku = “in/within the box” (more general). ndani ya sanduku emphasizes being enclosed “inside” the box.

What role does lililofungwa vizuri play, and how does it modify sanduku?

lililofungwa vizuri is a relative clause modifying sanduku, meaning “that has been closed well.” So sanduku lililofungwa vizuri = “the box that has been closed well.”

Can you break down lililofungwa into its morphemes?

Yes. lililofungwa =
• li- = subject/relative concord for sanduku
• -li- = past tense marker (“has been”)
• o = linking vowel for pronunciation
• fung- = verb root “close”
• -wa = passive suffix (“been closed”)

Why is there a linking vowel o in lililofungwa?

Swahili often inserts o to break up identical prefixes or awkward clusters. Here, li- + li- + fungwa → li-li-o-fungwa = lililofungwa.
