Conjunction — saying "and"

The rule

aur joins two things. Nouns, adjectives, whole sentences — the same word for all three.


Mi kupi pan aur ca.	I buy bread and tea.
Dom kabir aur sundar.	The house is big and beautiful.
Mi lai aur mi kan yu.	I come and I see you.
Angin aur yuki lai.	Wind and snow come.

Why the language needs a word here

Because two nouns side by side are already spoken for. The possession rule reads pan ca as “the tea’s bread” — so putting nouns next to each other cannot mean “and”. Without aur, Amadunia had no way at all to join two nouns.

Writing is worse off than speech here: a comma can stand in on the page, but in the air only a pause separates pan, ca from pan ca, and a pause is not a word.

Lists

For three or more, put aur between each pair:

Mi kupi pan aur ca aur akua.

In writing, commas may stand in for all but the last:

Mi kupi pan, ca aur akua.

Both are correct. The full form is never wrong, which is the form to teach first.

Sources

Spanish y, Portuguese and Italian e, Russian and Polish i, Latin et, Greek kai, Hindi and Urdu aur, Arabic wa, Indonesian dan, Swahili na, Chinese hé, Turkish ve — every language has one, and almost none of them agree.

aur is Hindi and Urdu, spoken by roughly eight hundred million people, and recognisable to Punjabi, Nepali and Bengali speakers besides.

Why this and not the alternatives

Almost every major word for “and” was blocked, and by the language’s own rules rather than by taste. Each was checked against the whole dictionary:

Candidate	Source	Reason rejected
na	Swahili, Igbo, Zulu	minimal pair with ba, ca, no, ta, ya
dan	Indonesian, Malay	minimal pair with din, kan, pan, uan
he	Chinese hé 和	minimal pair with hi, ke
et	Latin, French	minimal pair with es
kai	Greek	minimal pair with bai, fai, kab, kan, lai
kon	Spanish con	minimal pair with kan
kum	Latin cum	minimal pair with kim
sama	Indonesian	minimal pair with mama, nama, sasa, sema
plus	Latin, global	minimal pair with plis
ve	Turkish	the alphabet has no v
wa	Arabic wa و	the alphabet has no w
i	Spanish y, Russian, Polish	no collision at the time, but 41 roots end in -i — rafiki i mi, tri i du, beri i would blur in speech
e	Portuguese, Italian	one bare vowel; too light to carry a join
hem	Turkish, Persian	clean, but reaches far fewer people
gam	Hebrew	clean, but reaches fewer still

That so many candidates collide is not bad luck. Short common words crowd the same space, and aur survives partly because its shape — vowel, vowel, consonant — is one almost nothing else in the dictionary uses.

Open questions

~~“or”~~ — settled: o, Spanish/Italian o, Portuguese ou. Ca o akua? The language’s first one-letter word; the phonology allows a bare vowel, and 13 roots end in -o, so it blurs less than i would have.

Recounted September 5, 2026. It read only four roots end in -o, against twenty ending in -i; it is 13 against 41 today. That is the stale half. The other half is that neither figure was right when it was written: on the day o was settled the dictionary held six roots ending in -o — no, mano, go, hao, o itself and foto — and 22 ending in -i. The argument was stated as one in five and has never been better than one in three point seven; it is one in three point two now. So the comparison held all along and the margin never did, and the sentence that overstates it is the only thing on the page that ever said why o and not i. The word is settled and this changes nothing about that.

A second thing the recount shows: i is listed above as having no collision, and today it has one. o itself is a one-letter root now, so i and o are a minimal pair — the shortest one possible. The row is true of the day it was written and false of the dictionary it sits in, which is why it now says no collision at the time.
~~“with”~~ — settled in place.md: una + noun.
Joining more than two clauses — whether long chains want a different rhythm — is a question for when there is more prose.
There is no word for “but”. aur joins and o chooses; nothing contrasts. Found on September 4, 2026 in Lesson 12, which had been saying Ma hao! — an invented word — since it was written, for “but good!”. The lesson now says Hao! and says less. A briefing is now written: six pages have wanted one, lakin reaches five families with one word, and doing nothing is argued fairly. Whether the contrast is a conjunction, an adverb, or nothing at all is open; several source languages do without one in short speech, and Amadunia may too.
