Usipoivaa miwani yako, hutayaona maelezo vizuri kwenye ubao.

It breaks down as:

• u- = you (singular)
• -si- = negative
• -po- = if/when
• -i- = object marker referring to miwani
• vaa = wear / put on

So usipoivaa means if you do not wear it/them.

A natural English translation is if you don’t wear your glasses.

That -i- is an object marker. It stands for miwani inside the verb.

So the verb is not just usipovaa = if you don’t wear.
It is usipo-i-vaa = if you don’t wear them / it.

Swahili often puts the object inside the verb like this, especially when the object is specific and already known.

In Swahili, possessives usually come after the noun:

• miwani yako = your glasses
• kitabu chako = your book
• nyumba yako = your house

Also, the possessive must agree with the noun class.
Here miwani takes the possessive form yako.

So the order is:

• noun + possessive

not the English-style order.

It breaks down as:

• hu- = negative you (singular)
• -ta- = future
• -ya- = object marker referring to maelezo
• ona = see

So hutayaona means you will not see them.

In the sentence, them refers to maelezo.

Because maelezo belongs to the ma- noun class, and that class uses ya- as its object marker.

So:

• maelezo → object marker -ya-
• hutayaona = you will not see them

This is one of the key things to learn in Swahili: verbs often show the noun class of the object.

Yes, you often can.

A version without the object markers is still understandable and natural:

• Usipovaa miwani yako, hutaona maelezo vizuri kwenye ubao.

The version with object markers:

• Usipoivaa miwani yako, hutayaona maelezo vizuri kwenye ubao.

sounds a bit more explicit because the verb already points to the object. Swahili often allows both patterns, though speakers may prefer one or the other depending on style and emphasis.

In everyday use, miwani usually refers to glasses as a normal item, often what English would call a pair of glasses.

So even though English treats glasses as plural, Swahili uses miwani as the normal word for the object. What matters grammatically is its noun class, not whether English thinks of it as singular or plural.

So yes, miwani yako can mean your glasses = one pair of glasses.

Because grammatically maelezo belongs to the ma- class, which often behaves like a plural or collective noun class.

That is why the verb uses -ya- for it:

• maelezo → ya

Even if English translates it as something like details, information, or explanation, Swahili grammar still follows the noun class pattern.

So the grammar is based on noun class agreement, not on the exact English translation.

It can carry an if/when idea, depending on context.

In this sentence, if is the best translation:

• Usipoivaa miwani yako... = If you don’t wear your glasses...

So the idea is a condition: first this happens, then that result follows.

Kwenye is a very common locative word meaning something like:

• in
• on
• at

depending on context.

Here:

• kwenye ubao = on the board

This is a natural way to talk about writing or information appearing on a board.

If you said juu ya ubao, that would sound more literally like on top of the board or emphasize physical position. For writing shown on a board, kwenye ubao is more natural.

Vizuri means well / clearly here, and it modifies the idea of seeing.

So:

• hutayaona maelezo vizuri = you will not see the details clearly / well

In Swahili, adverbs like vizuri often come after the verb phrase. Its position here is very natural.

A helpful way to say them is:

• u-si-po-i-vaa
• hu-ta-ya-o-na

A few important pronunciation points:

• Swahili usually pronounces every vowel
• vaa has a long/doubled a sound
• yaona keeps both vowels; you do not squash them into one English-style sound

So try saying them smoothly, syllable by syllable:

• u-si-po-i-vaa
• hu-ta-ya-o-na
