INTRODUCTION TO MORPHOLOGICAL ANALYSER OF Apurinã LANGUAGE.

Definitions for Multichar_Symbols

Analysis symbols

The morphological analyses of wordforms for the Apurinã language are presented in this system in terms of the following symbols. (It is highly suggested to follow existing standards when adding new tags).

Tags for POS

Tags for sub-POS

Tags for Inflection

Tags for Case and Number Inflection

Possessive tags

Adjectival tags

Tenses

Verb person-number-gender

The Usage extents are marked using following tags:

The nominals are inflected in the following Case and Number

The comparative forms are: Numerals are classified under: Verb moods are: Verb personal forms are: object formed intransitive descriptive subject formed intransitive descriptive

Other verb forms are relativizer with subject reference kary/karu relativizer with object reference kyty/kytu

IPFTV PFTV perfective -pe

passivizer -~ka

Question and Focus particles:

Tags distinguishing different versions of the same lemma (before POS)

Semantics are classified with

Derivations are classified under the morphophonetic form of the suffix, the source and target part-of-speech. inhi verbal noun indicating instrument or result: ‘things to V with’ or ‘things to V’ (Facundes 2001: 240)

this is for contractions, which usually involve a personal pronoun followed by a verb or noun with word-initial vowel.

Morphophonology To represent phonologic variations in word forms we use the following symbols in the lexicon files:

**%^VowRM ** this will remove stem final vowel **%^VowNasL ** This will nasalize preceding vowel **%^VowY2I ** This will change stem-final y to i

And following triggers to control variation **%^I1 ** This will cause %{yiØ%}:i before all consonants

Symbols that need to be escaped on the lower side (towards twolc):

Flag diacritics

We have manually optimised the structure of our lexicon using following flag diacritics to restrict morhpological combinatorics - only allow compounds with verbs if the verb is further derived into a noun again: | @P.NeedNoun.ON@ | (Dis)allow compounds with verbs unless nominalised | @D.NeedNoun.ON@ | (Dis)allow compounds with verbs unless nominalised | @C.NeedNoun@ | (Dis)allow compounds with verbs unless nominalised

For languages that allow compounding, the following flag diacritics are needed to control position-based compounding restrictions for nominals. Their use is handled automatically if combined with +CmpN/xxx tags. If not used, they will do no harm. | @P.CmpFrst.FALSE@ | Require that words tagged as such only appear first | @D.CmpPref.TRUE@ | Block such words from entering ENDLEX | @P.CmpPref.FALSE@ | Block these words from making further compounds | @D.CmpLast.TRUE@ | Block such words from entering R | @D.CmpNone.TRUE@ | Combines with the next tag to prohibit compounding | @U.CmpNone.FALSE@ | Combines with the prev tag to prohibit compounding | @P.CmpOnly.TRUE@ | Sets a flag to indicate that the word has passed R | @D.CmpOnly.FALSE@ | Disallow words coming directly from root.

Use the following flag diacritics to control downcasing of derived proper nouns (e.g. Finnish Pariisi -> pariisilainen). See e.g. North Sámi for how to use these flags. There exists a ready-made regex that will do the actual down-casing given the proper use of these flags. | @U.Cap.Obl@ | Allowing downcasing of derived names: deatnulasj. | @U.Cap.Opt@ | Allowing downcasing of derived names: deatnulasj.

Subject Person marking

Object Person marking

For variant phonetics For prefix bad orthography

The word forms in Apurinã language start from the lexeme roots of basic word classes, or optionally from prefixes:
