IPA gabiridi (W) gabaridi (Kdj)
The r in the above is a quick tap of the tongue up against the top of your mouth. Linguists would call it an alveolar tap, a bit like the 'tt' in butter when you say the word quickly ba-da. In the spelling system of both Kunwinjku and Kundjeyhmi you spell this sound with a 'rr'.

kabirri- is the prefix on verbs (and some other classes of words) that means 'they 3 or more'
kabarri- is the Kundjeyhmi equivalent
The verb is -di, the verb to stand, exist, be.

About two years ago we had this same verb but with a different pronoun prefix ngahdi (nga-h-di) which means 'I am here, I am standing'. If the last sound of the pronoun prefix before the verb is both stressed and is a vowel, then the -di will change to -rri, where rr is the quick tapped sound when your tongue flicks up against the ridge behind your teeth.

nga-rri 'I'm here, I'm standing'
ka-rri 'he/she is here, he is standing, it is here'

In the past tense in Kunwinjku he/she was standing/existing the word would just be "di" without any prefix.
E.g. Boyen kumekke di dja bolkki kayakki.
Before it used to be [there] but it's not there today.

In Kundjeyhmi the same thing would be ba-rri. This is a difference between Kundjeyhmi and Kunwinjku. In the third person singular present tense, the prefix in Kunwinjku is ka- and the same in Kundjeyhmi ka- . But in the third person singular past tense prefix for verbs in Kunwinjku the prefix is zero i.e. you don't put anything on the verb. In Kundjeyhmi however you put ba-
Boyen kumekke ba-rri dja bolkkime kayakki. (Gdj)
Before it used to be [there] but it's not there today.

In the continuous past you say -dingihdi.
Dingihdi (W) Ba-rringihdi (Kdj) 'It used to be there'. This would be something that existed in a continuous or habitual sense.

Kunbarlanja kabirri-di. (W)
They are living at Gunbalanya.

Yika barrk djukerre mi-ngarre kabirri-di kure ku-rralk kabirri-karung kabirri-ni. (W)
Sometimes the black wallaroos stay in the thick bush, digging in the grass and sitting there.

Yiman ka-yime bu wadjbala barri-kukbele, kabarri-di kun-kuyeng kure ku-rrungbang kabarri-kurlahrung wanjh. (Kdj)
Like white skinned people, Europeans, if they stand out in the hot sun for a long time, they get sunburnt.
