Koci ya bayyana dabarar harbi ga kyaftin.

Yes, Koci is the subject, but in Hausa it is very normal for a full noun subject to be followed by a subject pronoun marker before the verb.

So:

• Koci = the coach
• ya = he / he did marker here
• bayyana = explained / made clear

This pattern is common in Hausa:

• Musa ya zo = Musa came
• Aisha ta zo = Aisha came

So Koci ya bayyana... is the normal way to say The coach explained...

Here ya is the 3rd person masculine singular subject marker in the completed/perfective form.

In simple terms, it means something like:

• he
• and it also helps show that the action is completed: explained

So ya bayyana means he explained or he made clear.

If the subject were feminine, you would usually get ta instead:

• Koci ta bayyana... = The coach explained... (if the coach is female)

Bayyana has the idea of making something clear, revealing, stating, or explaining depending on context.

In this sentence, explain is a very natural translation. So the sense is that the coach made the shooting strategy clear to the captain.

So bayyana is broader than just one English verb. Depending on context, it can mean things like:

• explain
• clarify
• make clear
• reveal
• state

This is because dabara changes form when it is linked to another noun.

• dabara = strategy / method / technique
• dabarar harbi = the strategy of shooting / shooting strategy

That -r is a linking form often seen when a noun is connected to what follows it. English uses of or puts one noun before another; Hausa often changes the first noun instead.

So:

• dabara = strategy
• dabarar harbi = shooting strategy

This is a very important pattern in Hausa.

Here harbi is functioning as a noun, meaning shooting or a shot, depending on context.

So in dabarar harbi, it means:

• strategy of shooting
• shooting strategy
• technique for shooting

Even though English often uses shooting as an -ing form, in Hausa harbi is simply a noun here.

Here ga means to in the sense of directing the explanation toward someone:

• ga kyaftin = to the captain

So the structure is:

• bayyana
  • thing explained + ga
    • person receiving the explanation

In other contexts, ga can have other meanings too, but in this sentence it is best understood as to.

This sentence uses a very normal Hausa order:

• Subject
• subject marker
• verb
• direct object
• prepositional phrase

So:

• Koci = subject
• ya = subject marker
• bayyana = verb
• dabarar harbi = what was explained
• ga kyaftin = to whom it was explained

This is the neutral, straightforward order. Hausa can sometimes move things around for emphasis, but this sentence is a basic standard pattern.

Hausa does not use articles the same way English does. There is no direct everyday equivalent of the or a/an that must appear in sentences like this.

So a noun like koci can mean:

• a coach
• the coach

and kyaftin can mean:

• a captain
• the captain

Which one is meant usually comes from context. Since you already know the meaning, the sentence is being understood as the coach and the captain.

They are loanwords, adapted into Hausa spelling and pronunciation.

• koci comes from English coach
• kyaftin comes from English captain

This is very common in Hausa, especially for modern professions, sports terms, ranks, and technology.

The spelling follows Hausa sound patterns, so the words look more Hausa even though their origin is English.

Hausa spelling represents sounds in a Hausa-based way, not in an English-based way.

So kyaftin is the Hausa adapted spelling of captain. The beginning reflects how the borrowed word is pronounced and fitted into Hausa sound patterns.

This kind of spelling adaptation is normal in Hausa loanwords. The goal is not to preserve English spelling, but to write the word in a way that suits Hausa pronunciation and orthography.

The main change would be the subject marker.

In your sentence:

• Koci ya bayyana... = The coach explained... (male singular)

If the coach were female:

• Koci ta bayyana...

If the subject were plural, the marker would change again.

So the important point is that the little subject word before the verb changes to match the subject. That is one of the first things learners need to watch for in Hausa sentences.

All three can work, depending on context.

• shooting strategy sounds natural in sports contexts
• shooting technique focuses more on how to shoot
• method of shooting is more literal but slightly less natural in everyday English

Since the sentence uses sports words like coach and captain, shooting strategy is probably the most natural overall translation here. But the Hausa phrase itself is broad enough to allow related meanings such as technique or method.
