Taught in Lesson 12, and extended in Lesson 18 for the case where the verb has an object.
The rule
An adjective placed straight after the verb describes the verb.
| Ta anda hayai. | She walks fast. |
| Mi kara hao. | I read well. |
| Anak kimbia kuat. | The child runs strongly. |
| Kita rabota cok. | We work a lot. |
No new word, no ending, no separate class of adverbs. The adjective does both jobs, and its position says which one.
This is what the language has been doing since Lesson 12 — Ta anda hayai — without ever stating the rule. It is stated now.
Before the object
When there is an object, the adverb stays with its verb:
| Mi kara hao libro ini. | I read this book well. |
| Ta beri hayai ca por mi. | She quickly gives me tea. |
Keeping the adverb against the verb is what makes it unambiguous. Put it after the object and it would attach to the object instead: Mi kara libro hao is “I read a good book”.
| Mi kara hao libro. | I read a book well. |
| Mi kara libro hao. | I read a good book. |
The word never changes; only its place does.
The full order
Everything the language has settled, in one line:
subject → no → suda/saufa → verb → adverb → object → place → time → clause
| Mi no suda kara hao libro ini in dom rat ini porke mi sedih. | I did not read this book well at home last night because I was sad. |
That sentence fills all nine slots at once, and not one word in it has changed its shape.
It read “Every rule in Amadunia is in that sentence” until September 5, 2026. Nine of the twenty-one rules are in it — order, negation, tense, the adverb, the demonstrative, place, time, the clause and the invariant pronoun. The copula, existence, the plural, possession, questions, verb chains, comparison, aur and the command are not, and a sentence cannot hold them all: a command has no subject, and a question is a question.
Sources
Using one form for adjective and adverb is the majority pattern: Chinese, Indonesian, Malay, Turkish (hızlı both ways), German (schnell both ways), Swahili, Japanese in part. English -ly and Romance -mente are the minority, and both come with irregulars — English good/well, fast/fast, hard/hardly.
Open questions
- Adverbs of degree on adverbs — “very quickly” — needs a word for “very”. cok is “much”; whether it covers “very” is untested. Wanted twice now: by the phrasebook, which lost it from “thank you very much”, and on September 4, 2026 by Mi parolas Esperanton tre flue, which came out as Mi sema hao Amadunia — I speak Amadunia well, with both the degree and the manner gone.
- Whether daima covers “forever”. It is glossed “always”, from Arabic dāʾiman, which carries both senses. Natura hidup daima would say nature lives forever, and Mi kula daima pan says I always eat bread — habit and endlessness in one word and one slot. Most languages separate them. This is the same shape of question as cok and “very” above, and it was found the same way: text 10 recorded that the language had no word for forever without checking what it did have.
- Frequency adverbs. daima (always) and kadang (sometimes) are adverbs by meaning but not adjectives. This page used to say they sit in the adverb slot with everything else; counted, most of them do not, and Lesson 19 alone uses all three positions. The split lived here as well as in the briefing until September 5, 2026, and only the briefing’s copy was recounted — one word, two pages, one check. A briefing measures it and costs the three answers. Until it is decided the word kadang cannot be written at all, because any sentence using it would settle the question by accident.
