Usisage pilipili manga nyingi sana; mtoto akila chakula hiki, atasema ni kali.

Usisage is a negative command addressed to one person: don’t grind or don’t pound.

It is built from:

• usi- = negative command marker for singular you
• -sag- = the verb root from kusaga (to grind / pound)
• -e = the final vowel used in this kind of negative command

So:

• saga! = grind!
• usisage! = don’t grind!

It is singular, so it means don’t grind when speaking to one person.

If you were talking to more than one person, you would say:

• msisage = don’t grind (you all)

This is a very common distinction in Swahili commands.

Pilipili manga is a fixed expression for black pepper or peppercorn pepper, as opposed to chili pepper in general.

So:

• pilipili by itself often means pepper / chili
• pilipili manga refers to the spice black pepper

A learner may notice that pilipili appears in both expressions, but the full phrase pilipili manga names a specific kind of pepper.

Nyingi comes from the adjective stem -ingi, meaning much / many / a lot. It changes form to agree with the noun class.

Here, pilipili manga takes the form nyingi.

So:

• pilipili manga nyingi = a lot of black pepper
• pilipili manga nyingi sana = very much / too much black pepper

Even though English usually treats pepper as uncountable, Swahili still uses its own noun-class agreement pattern.

Sana means very, a lot, or too much, depending on context.

In this sentence, it strengthens nyingi:

• nyingi = much / many
• nyingi sana = very much / far too much

Because the whole sentence is a warning, English naturally understands it as too much.

Akila means if he/she eats or when he/she eats.

It is made from:

• a- = he/she
• -ki- = a marker often meaning if or when
• -la = verb root from kula (to eat)

So:

• anakula = he/she is eating / eats
• akila = if/when he/she eats

In this sentence, akila introduces a condition:

• mtoto akila chakula hiki = if the child eats this food

Yes. The -ki- form often covers both ideas in Swahili, and the exact meaning depends on context.

So mtoto akila chakula hiki could be understood as:

• if the child eats this food
• when the child eats this food

In this sentence, because it sounds like a warning, if is the most natural English translation.

Because Swahili verbs normally include a subject marker, even when the subject noun is also stated.

So in:

• mtoto akila ... atasema ...

the noun mtoto gives the subject explicitly, but the verbs still need:

• a- = he/she

This is normal Swahili grammar.

Compare:

• mtoto anakula = the child is eating
• watoto wanakula = the children are eating

The verb changes to match the subject.

Atasema breaks down like this:

• a- = he/she
• -ta- = future marker (will)
• -sema = say

So atasema means:

• he/she will say

In the sentence:

• mtoto ... atasema ni kali = the child ... will say it is spicy

Because hiki must agree with the noun class of chakula.

• chakula belongs to noun class 7
• the this form for that class is hiki

So:

• chakula hiki = this food

This is a good example of Swahili agreement:

• kitabu hiki = this book
• kiti hiki = this chair
• chakula hiki = this food

Here, ni kali means it is hot/spicy.

• ni = is / it is
• kali = sharp, fierce, strong, hot, spicy, depending on context

With food, kali usually means:

• spicy
• hot (in the sense of chili heat, not temperature)

So the child would say:

• ni kali = it’s spicy

Not all Swahili adjectives behave the same way. Some adjectives change clearly with noun class, but others are commonly used in a more fixed form.

Kali is often used as a fairly stable form, especially in everyday expressions like:

• chakula ni kali = the food is spicy
• pilipili ni kali = the pepper is hot

So a learner should treat kali as a very common adjective meaning sharp / strong / spicy, and in this kind of sentence it does not need an obvious class prefix.

Mtoto means child (or sometimes baby), and it is gender-neutral.

So:

• mtoto can mean a boy child or a girl child
• a- on the verb means he/she, not specifically he

That is why English may translate it as:

• the child
• if the child eats this food, he or she will say it is spicy

The semicolon links two closely related parts:

• Usisage pilipili manga nyingi sana
• mtoto akila chakula hiki, atasema ni kali

It shows that the second part explains the reason for the first:

• Don’t grind too much black pepper; if the child eats this food, he/she will say it is spicy.

A full stop or sometimes a comma could also appear in similar writing, but the semicolon neatly connects the warning with its consequence.
