stem model f_U and declension #10

Open funderburkjim opened 6 years ago

funderburkjim commented 6 years ago

feminine nouns ending in 'U'

This list is derived from lexnorm-all2 by the simple filter: a) key1 ends in long vowel 'U' b) lexnorm is precisely 'f' (there are no cases where lexnorm is precisely 'f#U')

There are a few citations where 'f#U' appears as one of several alternatives; these cases will be handled by a later filter.

There are 310 distinct such cases, listed in file nominals/inputs/f_u1.txt.

endings for f_U model

The endings used for the f_U declension algorithm are:

Case	S	D	P
Nominative	UH	vO	vaH
Accusative	Um	vO	UH
Instrumental	vA	UByAm	UBiH
Dative	vE	UByAm	UByaH
Ablative	vAH	UByAm	UByaH
Genitive	vAH	voH	UnAm
Locative	vAm	voH	Uzu
Vocative	u	vO	vaH

Base for f_U model

We assume that the stem (last pada of key2) already ends in 'U'. The base then is formed by removing the final 'U'.

For example, the base for 'vaDU' is vaD.

f_U declension algorithm

The declension algorithm for feminine nouns ending in 'U' is procedurally the same as that for masculine nouns ending in 'a', with the exception of using the f_U endings.

Here is a summary of the procedure.

Start with key2.
If there are '-' characters in key2, represent key2 as H-X, where X is the last 'pada' and H is the head, with any additional '-' characters removed. If there are no '-' characters in key2, set H = '' (empty string) and X = key2.
construct the stem from X by removing the last character, which is 'U'. i.e., represent X as YU, where 'Y' is the base.
for each cell of the 24 declension cells, let E be the ending for that cell
- concatenate the base with the ending: Z = YE
- apply nR sandhi to Z, resulting in W.
- concatenate H with W. This is the declension of key2 for the given cell

example vaDU

Note that nR sandhi has no application in this example.

Case	S	D	P
Nominative	vaD + UH = vaDUH	vaD + vO = vaDvO	vaD + vaH = vaDvaH
Accusative	vaD + Um = vaDUm	vaD + vO = vaDvO	vaD + UH = vaDUH
Instrumental	vaD + vA = vaDvA	vaD + UByAm = vaDUByAm	vaD + UBiH = vaDUBiH
Dative	vaD + vE = vaDvE	vaD + UByAm = vaDUByAm	vaD + UByaH = vaDUByaH
Ablative	vaD + vAH = vaDvAH	vaD + UByAm = vaDUByAm	vaD + UByaH = vaDUByaH
Genitive	vaD + vAH = vaDvAH	vaD + voH = vaDvoH	vaD + UnAm = vaDUnAm
Locative	vaD + vAm = vaDvAm	vaD + voH = vaDvoH	vaD + Uzu = vaDUzu
Vocative	vaD + u = vaDu	vaD + vO = vaDvO	vaD + vaH = vaDvaH

Example karzU

The feminine noun karzU (a furrow) is declined as follows; note Genitive Plural where nR sandhi has an impact.

Case	S	D	P
Nominative	karz + UH = karzUH	karz + vO = karzvO	karz + vaH = karzvaH
Accusative	karz + Um = karzUm	karz + vO = karzvO	karz + UH = karzUH
Instrumental	karz + vA = karzvA	karz + UByAm = karzUByAm	karz + UBiH = karzUBiH
Dative	karz + vE = karzvE	karz + UByAm = karzUByAm	karz + UByaH = karzUByaH
Ablative	karz + vAH = karzvAH	karz + UByAm = karzUByAm	karz + UByaH = karzUByaH
Genitive	karz + vAH = karzvAH	karz + voH = karzvoH	karz + UnAm = karzUnAm -> karzURAm
Locative	karz + vAm = karzvAm	karz + voH = karzvoH	karz + Uzu = karzUzu
Vocative	karz + u = karzu	karz + vO = karzvO	karz + vaH = karzvaH

Irregular declensions not handled yet.

Remarks regarding f_I irregulars apply for the f_U model.

For example BU as a feminine (meaning the act of becoming or arising) is irregular.
Huet's BU f. declension recognizes some, perhaps all, of the irregularities but also differs in some spots with Kale on p. 43-4.
