Ko da yake ya tuntsure, rauninsa kaɗan ne.

Yes. Ko da yake is best learned as a fixed expression meaning although / even though. It introduces a concessive clause: something is true despite something else.

So in this sentence, ko da yake ya tuntsure sets up the idea although he ....

Because Hausa uses different pronoun forms in different jobs.

• ya = the normal 3rd person singular masculine subject form before a verb in this kind of clause
• shi = an independent or object form, not the normal subject form here

So ya tuntsure means he ... in a verbal clause. If the person were female, you would expect ta instead of ya.

ya + verb usually marks the completive/perfective in Hausa. Very often, that corresponds to English he did, he has done, or simply a past event.

So ya tuntsure refers to something that has already happened. The exact English tense depends on context.

Not necessarily. Hausa verbs often do not match one English word perfectly in every context.

The important point here is that tuntsure is the main verb describing the mishap or injury event. Depending on context, English may choose slightly different words. So it is better to learn how the Hausa verb is used in real sentences than to expect one perfect one-word equivalent every time.

rauninsa is a possessed noun form:

• rauni = injury, wound
• -n- = a linker used in possession
• sa = his

So rauninsa means his injury or his wound.

This is a very common Hausa pattern. Compare forms like littafinsa = his book.

kaɗan means little, small, or slight in this kind of context.

ne is a very common Hausa copular/focus particle. In sentences like this, it often does the job that English is does.

So:

• rauninsa kaɗan ne = his injury is slight / minor

Hausa often uses ne or ce where English would use a form of to be.

Because Hausa does not always mark time the same way English does, especially in nonverbal predicates like this one.

rauninsa kaɗan ne can be translated as:

• his injury is minor
• his injury was minor

The choice between is and was in English comes from the broader context, not only from ne itself.

Because this is a normal Hausa sentence pattern.

The structure is basically:

• rauninsa = the subject/topic
• kaɗan = the predicate
• ne = the copular/focus particle

So Hausa is not trying to copy English his injury is slight word-for-word. This Hausa order is natural.

The comma separates the concessive clause from the main clause:

• Ko da yake ya tuntsure = subordinate clause
• rauninsa kaɗan ne = main clause

In speech, there is often a small pause here. But the meaning mainly comes from ko da yake, not from the comma itself.

Yes, two especially common ones:

• ɗ in kaɗan is a special Hausa consonant, different from plain d
• ts in tuntsure is pronounced together as one sound, roughly like the ts in cats or at the start of tsunami

A rough syllable breakdown of tuntsure is tun-tsu-re. Listening to native audio is especially helpful for sounds like ɗ.
