Tafadhali angalia pindo la suruali ya mtoto kabla hajaenda shuleni.

Tafadhali means please. It makes the command more polite.

So:

• Angalia ... = Look at / Check ...
• Tafadhali angalia ... = Please look at / Please check ...

Without tafadhali, the sentence would sound more direct.

Angalia comes from the verb -angalia, which means look at, watch, or check/examine.

That fits this sentence because the speaker is asking someone to inspect something carefully, not just notice it.

Compare:

• kuona = to see
• kuangalia = to look at / check

So angalia pindo means something like check the hem or look at the hem.

Angalia is the singular imperative form, used when telling one person to do something.

So:

• Angalia! = Look!/Check! (to one person)
• Angalieni! = Look!/Check! (to more than one person)

In this sentence, the speaker is addressing one person, or using the singular as a general instruction.

The la is a possessive/genitive linker meaning of.

So:

• pindo la suruali = the hem of the trousers

The form of this linker changes depending on the noun class of the noun before it. Here, pindo belongs to a noun class that uses la.

So the important idea is:

• pindo = hem
• la = of
• suruali = trousers

Together: hem of the trousers

Because there are two of relationships stacked together:

1. pindo la suruali = the hem of the trousers
2. suruali ya mtoto = the child’s trousers

Put together:

• pindo la suruali ya mtoto = the hem of the child’s trousers

The connector changes shape depending on the noun it goes with:

• la agrees with pindo
• ya agrees with suruali

This is very normal in Swahili.

Suruali normally means trousers / pants as a whole garment.

So pindo la suruali is talking about the hem of the trousers, not just a random piece of cloth.

Depending on context, English might say:

• the hem of the trousers
• the trouser hem
• sometimes just the pants hem

Because mtoto simply means child and does not tell you gender.

So mtoto can mean:

• a child
• the child
• boy or girl, if the context makes it clear

Likewise, in hajaenda, the subject is he/she because Swahili does not mark gender there.

So the sentence does not tell us whether the child is male or female.

Swahili normally does not use articles like English a/an/the.

So nouns like:

• mtoto
• suruali
• pindo

can mean a child, the child, trousers, the trousers, etc., depending on context.

That means the exact English article is chosen from the situation, not from a separate word in the Swahili sentence.

It means before he/she goes or before he/she has gone.

This is a very common Swahili pattern:

• kabla = before
• kabla + subject + negative perfect form = before the subject does/has done something

So:

• kabla hajaenda literally looks like before he/she has not gone
• but in normal Swahili usage it means before he/she goes / before he/she has gone

It expresses that the action of going has not yet happened at that point.

Formally, it is a negative perfect form:

• ha- = negative marker for he/she
• -ja- = perfect-related marker in this negative form
• enda = go

So hajaenda by itself often means he/she has not gone.

But after kabla, this form is commonly used with the meaning before he/she goes/has gone.

So in this sentence, you should understand it as part of the whole expression kabla hajaenda, not as a simple standalone negative statement.

Shuleni is the locative form of shule.

• shule = school
• shuleni = at school / to school / in school

The ending -ni often marks location or destination.

So:

• ameenda shule can occur in some contexts, but
• ameenda shuleni clearly means has gone to school / is at school

In this sentence, shuleni fits the idea of the child going to school.

Yes, Swahili often uses another pattern:

• kabla ya kwenda shuleni = before going to school

But that version does not state the subject directly.
In your sentence, kabla hajaenda shuleni, the subject is clearer because it refers specifically to the child.

So the difference is roughly:

• kabla ya kwenda shuleni = before going to school
• kabla hajaenda shuleni = before he/she goes to school

It breaks down like this:

• Tafadhali = please
• angalia = check / look at
• pindo la suruali ya mtoto = the hem of the child’s trousers
• kabla hajaenda shuleni = before he/she goes to school

So the structure is:

Please + check + noun phrase + before-clause

This is a very natural Swahili way to give a polite instruction with a time condition.
