Questions & Answers about Tafadhali funga bomba vizuri; maji yanapotea kwa sababu ya bomba hilo.

In this context, does "funga bomba" mean "turn off the tap" or literally "tie/lock the tap"?

Here, funga bomba means “close/turn off the tap.” In everyday Swahili:

• funga = close/shut (a tap, door), lock
• fungua = open (a tap, door)
• zima = turn/switch off (lights, engine, fire), not usually a tap

So you say: funga bomba (close the tap) and fungua bomba (open the tap). You’d say zima taa (turn off the light), not “funga taa.”

What exactly does "bomba" mean—tap, faucet, or pipe?

Bomba can mean both “tap/faucet” and “pipe,” and context tells you which. In many contexts like this one, it’s the tap. Plural is mabomba. Regionally, some people also say mfereji in “tap water” (maji ya mfereji), but for the physical tap/faucet itself, bomba is the safest and most common choice. Note: in slang (esp. Kenya), bomba can mean “awesome,” but that’s not the meaning here.

Why "vizuri" and not "nzuri"? Are they interchangeable?

• vizuri is an adverb: “well/properly.” So funga bomba vizuri = “close the tap properly.”
• nzuri is an adjective agreeing with certain noun classes: “good/nice.” They aren’t interchangeable in this sentence. You could also use vyema (also spelled vema) as a slightly more formal/old-fashioned synonym of “properly.”

Why is it "maji yanapotea" and not "maji inapotea"?

Maji (“water”) behaves like a class 6 plural noun (ma- class). Verbs agreeing with class 6 use the subject marker ya- in the present: ya- + na- + verb → yanaverb. So:

• Correct: maji yanapotea (“water is being lost/disappearing”)
• Wrong: maji inapotea (the i- subject marker fits class 9/10, not class 6)

What does "yanapotea" break down into, and what aspect does it convey?

• ya- (class 6 subject marker for maji)
• -na- (present/progressive/habitual)
• potea (verb “be lost/disappear”) So yanapotea ≈ “are being lost/are disappearing” (ongoing or general/habitual, depending on context).

Would "yanavuja" or "yanamwagika" be better than "yanapotea" for water?

Often, yes:

• kuvuja = to leak (best when the tap/pipe is faulty): Maji yanavuja kutoka kwenye bomba hilo.
• kumwagika = to spill (accidentally pour out): Maji yanamwagika.
• kupotea = to be lost/disappear (more general). If you want “you’re wasting water,” you could say: Unapoteza maji.

Why is it "kwa sababu ya bomba hilo"—why "ya" and not "la"?

The -a “of” agreement is with the head noun sababu (reason), not with bomba. Sababu is class 9, and the class-9 associative is ya. Hence:

• kwa sababu ya
  • X = “because of X” Even if X is class 5 (bomba), you still use ya because it agrees with sababu, not with X.

Why "hilo" after "bomba"? Could I say "bomba hili" or "lile" instead?

Demonstratives typically follow the noun: bomba hilo. For class 5 nouns (like bomba):

• hili = this (near speaker)
• hilo = that (near listener/already mentioned)
• lile = that (far/over there) You can front them (hilo bomba) for emphasis, but the neutral position is after the noun. Choose hili/hilo/lile according to distance/reference.

Do I have to repeat "bomba" in the second clause, or can I just say "kwa sababu ya hilo"?

You can say kwa sababu ya hilo (“because of that”) if the referent is crystal clear from context. Repeating bomba makes it explicit and avoids any ambiguity, which is why kwa sababu ya bomba hilo is natural here.

Could I join the clauses with "kwa sababu" instead of a semicolon?

Yes. Options include:

• Period: Tafadhali funga bomba vizuri. Maji yanavuja…
• Conjunction: Tafadhali funga bomba vizuri kwa sababu maji yanapotea…
• Clause after “kwa sababu”: Tafadhali funga bomba vizuri, kwa sababu bomba hilo linavuja. The semicolon is also fine—punctuation follows English-like conventions.

Any other natural ways to make the request politely?

Yes:

• Naomba ufunge bomba vizuri. (I request that you close the tap properly.) Note the subjunctive ufunge after naomba.
• Tafadhali, usisahau kufunga bomba. (Please don’t forget to close the tap.)
• Tafadhali funga bomba kabisa. (Please close the tap completely.)

How do I say “close it tightly/completely” rather than just “well”?

Use intensifiers:

• kabisa (completely): Funga bomba kabisa.
• vizuri sana (very well): Funga bomba vizuri sana.
• If you mean “tighten it a bit”: Funga bomba kwa nguvu kidogo (literally “with a bit of force”).

Where can "vizuri" go in the sentence? Before or after the verb?

It’s flexible, but most natural is after the object:

• Most common: Funga bomba vizuri.
• Also possible: Funga vizuri bomba. (acceptable, but less common) Keeping vizuri near the verb is usual.

Is "sababu ya" without "kwa" also correct?

Without kwa, sababu ya means “the reason for,” not “because of.” For “because of,” use kwa sababu ya.

• Kwa sababu ya mvua, hatuendi. (Because of the rain, we’re not going.)
• Sababu ya mkutano ni kutangaza matokeo. (The reason for the meeting is to announce the results.)

What noun-class agreement would adjectives take with "bomba" and "maji"?

• bomba (class 5): adjectives take the class-5 form, e.g. bomba zuri (“a good tap”), bomba hili (this tap).
• mabomba (class 6 plural): mabomba mazuri (good taps).
• maji (class 6): e.g. maji mengi (a lot of water), maji machafu (dirty water). Remember, nzuri is for class 9/10 nouns (e.g., chai nzuri), not for class 5/6.

How would I say “The tap is leaking” directly?

• Bomba linavuja. If you want to keep the original structure but make the cause explicit:
• Maji yanavuja kwa sababu bomba hilo linavuja.
• Or more idiomatically: Maji yanavuja kutoka kwenye bomba hilo.
