Mun tattauna yiwuwar canji.

Mun is the Hausa first-person plural completed-action subject form. In this sentence, it corresponds to we in a meaning like we discussed or we have discussed.

So mun is not just a plain standalone pronoun like English we; it already includes the sense that the action is completed.

Because Hausa changes the subject form depending on the kind of clause and the aspect/mood.

• mun tattauna = we discussed / we have discussed
• mu tattauna usually means something like let's discuss

So if you want a normal statement about a completed action, mun is the correct form.

Not exactly in the same way English thinks about tense. Hausa often focuses more on aspect than on strict tense.

Here, mun marks a completed action, so in English this is often translated as:

• we discussed
• or we have discussed

Which English version sounds best depends on context.

Tattauna means to discuss.

In this sentence, it is the main verb. It takes a direct object, so the thing being discussed comes right after it:

• Mun = we
• tattauna = discussed
• yiwuwar canji = the possibility of change

So the structure is very straightforward.

It literally breaks down as:

• yiwuwa = possibility
• canji = change

Together, yiwuwar canji means possibility of change.

The -r is a linking/construct ending used when this noun is connected to another noun after it.

So:

• yiwuwa = possibility
• yiwuwar canji = possibility of change

This is one way Hausa expresses a relationship that English often shows with of.

Because Hausa often does not need a separate word like English of in this kind of phrase.

English says:

• the possibility of change

Hausa can express that idea structurally with:

• yiwuwar canji

So the relationship is built into the noun phrase itself rather than using a separate word.

Hausa does not use the in the same way English does. Very often, definiteness is understood from context.

So even though English may translate this as the possibility of change, Hausa can simply say yiwuwar canji without adding a separate word for the.

The order is:

subject marker + verb + object

So here:

• Mun = we
• tattauna = discussed
• yiwuwar canji = the possibility of change

That gives:

Mun tattauna yiwuwar canji.

A natural negative version is:

Ba mu tattauna yiwuwar canji ba.

This means We did not discuss the possibility of change.

A common Hausa negative pattern is:

Ba ... ba

So you put ba before the clause and another ba at the end.
