Ninafuatilia mapato kila mwezi.

Ninafuatilia has three main parts:

• ni- = I
• -na- = a present-time marker
• fuatilia = monitor / track / follow up on

So ninafuatilia means I am tracking, I track, or I am monitoring, depending on context.

In Swahili, the subject is usually built into the verb.

So instead of saying a separate word for I, Swahili often uses the subject prefix ni- on the verb itself.

• ni-na-fuatilia = I am tracking

You can add mimi for emphasis:

• Mimi ninafuatilia mapato kila mwezi.

That would mean something like I am the one who tracks income every month or As for me, I track income every month.

This is a very common question.

• kufuata usually means to follow, to go after, or sometimes to obey
• kufuatilia means to follow something closely, to monitor, to track, or to follow up on

So in this sentence, kufuatilia is the better choice because the idea is not just physically following something, but keeping track of it regularly.

Mapato means income, earnings, revenue, or receipts, depending on context.

It often refers to money coming in, such as:

• personal income
• business revenue
• government revenue

So in this sentence, mapato is the thing being tracked.

Mapato belongs to a Swahili noun class that often uses ma- in the plural.

Its singular form is pato, but in real usage mapato is much more common, especially when talking about income/revenue in a general sense.

So learners will often see mapato even when English might use the singular word income.

Because Swahili and English do not always package ideas the same way.

In Swahili, mapato is grammatically plural in form, but in English the most natural translation is often the mass noun income.

So:

• Ninafuatilia mapato kila mwezi
  = I track income every month

Even though mapato is plural in form, you do not have to force a plural translation like incomes unless the context specifically calls for it.

After kila meaning each / every, Swahili normally uses the singular noun.

So:

• kila mwezi = every month
• not kila miezi

This is similar to other expressions:

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

Even though English sometimes feels plural in meaning, Swahili keeps the noun singular after kila.

The marker -na- usually shows present time.

Depending on context, it can mean:

• I am tracking (right now / currently)
• I track (habitually or regularly)

Because the sentence includes kila mwezi meaning every month, the natural interpretation is habitual:

• I track income every month

So here -na- is best understood as a present habitual action.

Good question. In Swahili, an object marker is often optional when the full object noun is already stated.

So this sentence is perfectly natural:

• Ninafuatilia mapato kila mwezi.

Because mapato is explicitly present, the object is already clear.

You could also hear:

• Ninayafuatilia mapato kila mwezi.

Here ya- is the object marker agreeing with mapato. This can add emphasis or make the object feel more specifically identified, but it is not required in a simple sentence like this.

If the noun were omitted, the object marker could stand in for it:

• Ninayafuatilia kila mwezi.
  = I track them every month.

Yes, a little.

The basic order here is:

• verb + object + time expression

So:

• Ninafuatilia mapato kila mwezi.

This is very natural.

You can also move the time expression for emphasis:

• Kila mwezi ninafuatilia mapato.

That means the same thing, but it puts more focus on every month.

Both are correct, though the original sentence is a very standard neutral order.

You add a possessive or a connecting phrase after mapato.

For example:

• Ninafuatilia mapato yangu kila mwezi.
  = I track my income every month.

• Ninafuatilia mapato ya kampuni kila mwezi.
  = I track the company’s revenue every month.

So mapato can easily be made more specific if needed.
