Non-repetition in Polish locative suffixes -ni, -alni, -arni, -owni
Materials from Elzbieta Górska, "Formal and functional restrictions on the productivity of word formation rules (WFRs)"
Polish has 4 suffixes with "Locative case" meaning ("closed area, room" especially "Workshop, warehouse"), -ni, -alni, -arni, -owni, as described in Elzbieta Górska, "Formal and functional restrictions on the productivity of word formation rules (WFRs)", Nordic journal of linguistics 5, 1982, s. 77-89. The main topic of the article is the concept of productivity and its importance for the place of word derivation in a generative grammar, and the description has sections on syntactic, morphological and semantic conditions for word bases, and conditions for the derivation of words ("output conditions").
Here, we only consider one part of the article. P. 82 we find a very brief paragraph: "Conditions on the Phonological form of bases. No restrictions of this type can be found in the data considered here, ..". However, it is apparent from the article (p. 80 and 83) that there are the following four constraints on the use of these suffixes:
1) -alni is used by verbs in -a but without -l- the base.
2) -ni is only used by verbs in -ow and by two groups of nouns, namely agent nouns in -arz and words in -er, -or, -ator.
3) -arni is used mostly by verbs in -i (but also by nouns).
4) -owni is used by nouns of any kind (no constraint).
In other words, synchronically considered, the system of locative suffixes has the following phono-morphological restrictions:
1) From verbs in -ow cannot be derived locatives with -ow (there is of course a historical correlation between verbs -ow and the suffix -owni).
2) Of verbs with -l- in the base cannot be derived locatives with the suffix -alni.
3) Deriving locatives from verbs in -ow with the suffix -arni, the ending -ow is dropped: -ow-arni > -arni, i.e. the -ow of the verb, which is substantially identical with the locativsuffix -ow, would, together with -arni, seem a repetition, namely of the content (!), not as expression.
In terms of formulas, we have three restrictions:
1) -l-alni -> -l-arni.
2) -ow-owni -> -owni.
3) -ow-arni -> -arni.
1) Is a clear non-repetitive function (of phono-morphological nature).
2) Is synchronically similar, but historically it's probably not a good description.
3) Is very interesting, since the sequence -ow-arni apparently is perceived as a repetition, because of the semantic equation -owni = -arni, and therefore is subjected to a non-repetitive restriction, not on a phono-morphological, but on a morpho-semantic level.
We have a mini-universe of derivation with three different kinds of non-repetition, one is classic, one is a kind of haplology, one is morpho-semantic.
