Kila nahau ina fasili yake, lakini si kila methali ina maana ya moja kwa moja.

Kila means each or every. It appears twice because the sentence makes two separate general statements:

• Kila nahau ina fasili yake = every idiom has its own definition
• si kila methali ina maana ya moja kwa moja = not every proverb has a literal meaning

So the repetition is completely natural. In English, we also often repeat every in this kind of contrast.

They are related, but not the same:

• nahau = an idiom, a fixed expression whose meaning may not be obvious from the individual words
• methali = a proverb, a traditional saying that expresses wisdom or advice

So nahau is closer to an idiomatic phrase, while methali is a proverb.

Ina means it has for nouns in this noun class.

Both nahau and methali belong to the noun class that usually takes i- / zi- agreement. In the singular, the subject marker is i-, and with -na (have), that becomes ina.

So:

• nahau ina... = the idiom has...
• methali ina... = the proverb has...

This is noun-class agreement, which is very important in Swahili.

Yake means its, his, her, or their, depending on context. Here it means its own.

So:

• fasili yake = its definition / its own definition

In this sentence, yake refers back to nahau.

Si kila means not every.

It does not mean no or none. That distinction matters:

• si kila methali... = not every proverb...
  • meaning: some proverbs do, but some do not
• If you wanted no proverb..., that would be a much stronger statement

So the sentence is making a limited negative statement, not a total one.

Often, yes. Si is commonly used for negation, especially in identification or simple contrastive statements.

In this sentence:

• lakini si kila methali... = but not every proverb...

So here si is negating kila methali.

Learners should notice that Swahili negation is not always done in one single way; it depends on the sentence structure. But here, si is the natural form.

They are similar, but not identical.

• fasili = definition, explanation, interpretation
• maana = meaning, sense

In this sentence, the distinction is useful:

• an idiom has a definition/explanation: fasili
• a proverb may or may not have a literal meaning: maana ya moja kwa moja

So fasili sounds a bit more like a formal explanation, while maana is the general idea of meaning.

It means literal meaning or direct meaning.

Breaking it down:

• maana = meaning
• ya = of
• moja kwa moja = direct, straightforward

So literally it is something like meaning of directness, but in natural English it means literal meaning or direct meaning.

The ya agrees with maana.

Maana is a noun in the same general noun class as many loanwords and class 9 nouns, and the associative connector for that class is often ya.

So:

• maana ya moja kwa moja = meaning of a direct kind / literal meaning

This -a construction is very common in Swahili:

• kitabu cha mwanafunzi = the student's book
• maji ya kunywa = drinking water
• maana ya moja kwa moja = literal meaning

Yes, in practice it functions like a set phrase.

Moja kwa moja often means:

• direct
• straightforward
• literal
• immediately, depending on context

In this sentence, it clearly means direct/literal, not immediately.

So learners should understand it as a fixed expression whose exact English translation depends on context.

Swahili does not usually use articles like English does.

So:

• nahau can mean an idiom, the idiom, or idioms in the right context
• methali can mean a proverb or the proverb, depending on context

Here, kila already gives the meaning clearly:

• kila nahau = every idiom
• kila methali = every proverb

So no article is needed.

Yes. It is very natural.

The basic pattern is:

• Kila nahau ina fasili yake
  • subject: kila nahau
  • verb: ina
  • object/complement: fasili yake

Then:

• lakini si kila methali ina maana ya moja kwa moja
  • lakini = but
  • si kila methali = not every proverb
  • ina = has
  • maana ya moja kwa moja = literal meaning

This is a normal and clear way to structure the thought.

They are usually treated as class 9 nouns in the singular, which is why they take i- agreement:

• nahau ina...
• methali ina...

This matters because noun classes affect:

• subject markers
• object markers
• possessives
• connectors like ya, cha, wa, and so on

For a learner, the big practical point is this: when you learn a noun, also notice the agreement it triggers.

Yes. A very literal breakdown would be:

• Kila nahau = every idiom
• ina = has
• fasili yake = its definition
• lakini = but
• si kila methali = not every proverb
• ina = has
• maana ya moja kwa moja = a direct/literal meaning

So a close literal version would be:

Every idiom has its definition, but not every proverb has a direct meaning.

In smoother English, that becomes something like Every idiom has its own explanation, but not every proverb has a literal meaning.
