root-morphology

Estonian morphological tags

part of speech

  • +Symbol = independent symbols in the text stream, like £, €, ©

derivation suffixes, used to filter out illegal combinations internally

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

  • »7 = literal », as plain » is reserved for use as a derivation morpheme boundary symbol
  • «7 = literal «, as plain « is reserved for use as a derivation morpheme boundary symbol
  • [>] = literal > escaped with square brackets, to avoid collision with > as morpheme boundary)
  • [<] = literal < escaped with square brackets, to avoid collision with < as morpheme boundary)

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.
