The Kadu were the dominant ethnic group in the Chindwin River valley at the beginning of the early 2nd millennium A.D. until the Chin people and subsequently the Shan people migrated into the Chindwin Valley (Matisoff 2013:13).^[5]

Nouns edit

Abstract nouns such as freedom, love, experience, and anger are not attested in the Kadu noun class. They are usually expressed by verbs or adjectival verbs.

The language has two categories of nouns:

1, So called "simple nouns" are treated as monomorphemic by the native speakers.

2, Nouns known as "complex nouns" are polymorphemic, and most of the complex nouns come from the process of compounding.

Verbs edit

Adjectives that expresses dimensions and qualities such as "tong" (=big) and "lom" (=warm) function as verbs, and are categorized as verbs.

The verbs are structurally categorized as:

1, Simple verbs, which are treated as monomorphemic words by the native speakers.

and

2, Polymorphemic complex verbs.

Kadu verbs may be reduplicated using the same morpheme or may take attendant words to express the repeated or frequent actions.

V-V constructions function as resultative, directional, evaluative, explanatory, or manner.

Adverbs edit

The adverbs are also "simple" or "complex" like nouns and verbs.

One thing to point up is that the complex adverbs are derived from verbs or nominals by the processes of reduplication or semi-reduplication.

Numerals edit

Kadu has retained native numerals for only the numerals one, two, three, and four.^[7] Other numerals have been supplanted by Tai Laing and Burmese numerals.^[7][8][9]

Numerals are always attached to classifiers, although classifiers do not occur with multiples of ten.

As for ordinal numbers, Burmese ordinal numbers are used because the original ordinal numbers are already lost.

Pronouns edit

Quantifiers edit

Quantifiers follow the head noun they quantify.

Particles edit

There are nominal relational markers, verbal particles, clausal particles, utterance final particles, and speaker attitude particles.

Interrogatives edit

Yes/no interrogatives edit

Yes/no questions are formed by simply adding either of the two interrogative particles "la" and "ka" at the end of the phrase.

Alternative questions edit

Yes/no questions can also be expressed by an alternative interrogative expression like "is it A or not A", which can be found in Mandarin Chinese as well.

Tag questions edit

Interrogative sentences can be made by adding "chi" (=true) at the end of sentences, like "right?" in English language.

Wh- questions edit

Wh- questions are formed by attaching the Wh-word forming morphemes, "  ma" or "  ha", to specific nomials or nominal postpositions.

Wh- question words also may function as indefinite pronouns such as "whatever", "anyone" and so on.

Negation edit

Verbs can be negated by negative proclitics, "a-" and "in-".^[3]
