Kila jioni ninajaribu kukariri maneno mapya kabla sijalala.

Yes. Kila jioni means every evening.

• kila = every / each
• jioni = evening

So together:

• kila jioni = every evening

In Swahili, time expressions like this often come near the beginning of the sentence, just like in English:

• Every evening, I try...

Also, kila does not usually change form. You can use it with many nouns:

• kila siku = every day
• kila wiki = every week
• kila mwaka = every year

Ninajaribu can be broken down like this:

• ni- = I
• -na- = present / ongoing tense
• jaribu = try

So:

• ni + na + jaribu → ninajaribu
• meaning: I try / I am trying

This is a very common Swahili verb pattern:

subject prefix + tense marker + verb stem

For example:

• ninasoma = I am reading / I read
• ninakula = I am eating
• ninaandika = I am writing

In this sentence, ninajaribu is naturally understood as I try.

Because kukariri is the infinitive form of the verb, like to memorize in English.

• ku- = infinitive marker, like to
• kariri = memorize / recite by heart

So:

• kukariri = to memorize

After verbs like try, want, like, begin, Swahili often uses the infinitive:

• ninajaribu kukariri = I try to memorize
• ninataka kusoma = I want to read
• napenda kuimba = I like to sing

So this part works very much like English:
I try to memorize...

Kukariri often means to memorize, to learn by heart, or to recite from memory.

Depending on context, it can suggest:

• repeating something until it sticks in your memory
• memorizing words, lines, facts, or passages
• reciting something you have memorized

In this sentence, kukariri maneno mapya is best understood as:

• to memorize new words

So yes, memorize is the most natural English match here.

Because mapya has to agree with maneno in noun class.

Here is the breakdown:

• neno = word
• maneno = words

maneno is a plural noun, and it belongs to a noun class that takes adjective agreement like ma-.

The adjective -pya means new.
When it agrees with maneno, it becomes:

• mapya = new

So:

• maneno mapya = new words

Compare:

• neno jipya = a new word
• maneno mapya = new words

This is one of the most important features of Swahili: adjectives change to match the noun class.

Because in Swahili, adjectives usually come after the noun they describe.

So:

• maneno mapya = words new = new words

This is normal Swahili word order.

More examples:

• kitabu kizuri = good book
• watoto wadogo = small children
• nyumba kubwa = big house

So if you are thinking in English order, you have to mentally flip it:

• noun first
• adjective second

This means before I sleep or before I go to sleep.

Breakdown:

• kabla = before
• sijalala = literally something like I have not yet slept / before I have slept, but in this structure it means before I sleep

The full phrase:

• kabla sijalala = before I sleep / before going to sleep

This is a very common Swahili pattern after kabla.

This is one of those structures that feels a little different from English.

Sijalala breaks down as:

• si- = negative subject marker for I
• -ja- = “not yet” / negative perfect-related marker
• lala = sleep
• final -a

So:

• sijalala = I have not slept yet

After kabla (before), Swahili often uses this kind of form to express something that has not yet happened by that point.

So:

• kabla sijalala literally feels like before I have slept
• natural English: before I sleep / before going to bed

This is idiomatic Swahili, so it is best learned as a common pattern.

Yes, absolutely.

• kabla ya kulala = before sleeping / before going to sleep
• kabla sijalala = before I sleep / before I go to sleep

Both are natural, but they are structured differently:

1. kabla ya + infinitive

   • kabla ya kulala
   • more like before sleeping

2. kabla + clause

   • kabla sijalala
   • more like before I sleep

The version in your sentence is slightly more personal because it explicitly includes I.

It can suggest either, depending on context.

• kulala literally means to sleep
• but in everyday use, it can also mean to go to bed or to fall asleep, depending on the situation

In this sentence:

• kabla sijalala

the most natural English translations are:

• before I sleep
• before I go to sleep
• before bed

All of these fit the idea.

The sentence is:

Kila jioni ninajaribu kukariri maneno mapya kabla sijalala.

A helpful way to see it is:

• Kila jioni = every evening
• ninajaribu = I try
• kukariri = to memorize
• maneno mapya = new words
• kabla sijalala = before I sleep

So the overall order is:

time expression + verb + infinitive + object + time clause

This is very natural in Swahili.

A smooth literal gloss would be:

• Every evening I try to memorize new words before I sleep.

No, not naturally.

Mapya is an adjective meaning new, and it needs a noun to describe. By itself, it does not clearly tell the listener new what?

So:

• maneno mapya = new words

If you leave out maneno, the phrase sounds incomplete unless the noun is already very clear from context. For learners, it is best to keep the full phrase.

Yes, the main verb is in the present/habitual form:

• ninajaribu = I try / I am trying

Because the sentence begins with kila jioni (every evening), the meaning is habitual:

• Every evening, I try...

So in natural English, this is not just about right now. It describes a routine or repeated action.
