Yabanya tana girma, saboda haka noma zai ba da amfanin gona.

Because tana is the feminine singular agreement form used here for an ongoing action. In this sentence, Yabanya is being treated as a feminine singular noun.

This does not have to mean female in a biological sense. In Hausa, many nouns have grammatical gender, so even things that are not people can take masculine or feminine agreement.

Not exactly. tana is doing more than English is.

It shows:

• the subject is feminine singular
• the action is ongoing / in progress

So tana girma is best understood as it/she is growing, not as a simple one-word translation of is.

Here, girma means growing, becoming bigger, or increasing.

In Hausa, forms like tana are often followed by a verbal noun or verb-like form. So tana girma literally looks more noun-like than English, but the natural meaning is simply is growing.

Because Hausa builds this idea differently from English. Instead of using a form exactly like to be + -ing, Hausa uses:

• a subject/agreement marker like tana
• plus the action word, here girma

So the meaning of is growing is spread across the whole phrase tana girma.

saboda often means because of or because.

saboda haka literally means because of that, and very often means:

• therefore
• so
• as a result

So in this sentence, saboda haka connects the first idea to its result.

Here it is functioning as a noun: farming or agriculture.

This is very common in Hausa. A form related to a verb can be used as a noun-like subject in a sentence. So noma zai... means something like farming will...

Because zai is the masculine singular future form, roughly like will for a masculine singular subject.

In this sentence, noma is treated as a masculine noun, so Hausa uses zai:

• noma zai... = farming will...

If the subject were feminine singular, you would expect za ta instead.

ba da is a common Hausa verbal expression meaning to give, to provide, or sometimes to produce/yield, depending on context.

You should learn ba da as a unit. Hausa has a number of verbs like this that work as multi-word expressions rather than a single English-style verb.

Here, zai ba da amfanin gona means will provide / yield crop produce.

It means crop yield, produce, or harvest.

Literally, it is something like the benefit/use of farming/the farm, but in normal usage it refers to agricultural produce or yield.

So even if the literal pieces seem unusual, the full expression is best learned as crop yield / harvest / produce.

The -n is a linker that connects nouns in Hausa. It often works like of in English.

So:

• amfani = benefit/use
• gona = farm/field
• amfanin gona = produce of the farm or agricultural produce

This kind of noun linking is very common in Hausa.

Because Hausa does not use articles the way English does. There is no obligatory word exactly like the or a/an before nouns in ordinary sentences.

Whether a noun is understood as definite or indefinite usually comes from:

• context
• word order
• other words in the sentence

Because the sentence describes:

• something happening now: tana girma
• a result that will happen later: zai ba da

So the structure is basically:

• current situation
• therefore
• future result

That is a very normal pattern in Hausa.
