Primitive words and roots of words
In the algebraic theory of codes and formal languages, the set Q of all primitive words over some alphabet Σ has received special interest. With this survey article we give an overview about relevant research to this topic during the last twenty years including own investigations and some new results. In Section 1 after recalling the most important notions from formal language theory we illustr...
متن کاملTwin-roots of words and their properties
In this paper we generalize the notion of an ι-symmetric word, from an antimorphic involution, to an arbitrary involution ι as follows: a nonempty word w is said to be ι-symmetric if w = αβ = ι(βα) for some words α, β . We propose the notion of ιtwin-roots (x, y) of an ι-symmetric wordw. We prove the existence and uniqueness of the ι-twin-roots of an ι-symmetric word, and show that the left fac...
متن کاملDirectional Asymmetries in the Morphology and Phonology of Words, with Special Reference to Bantu
This paper is concerned with two types of word-level asymmetries and their interaction: leftright asymmetries and stem-word asymmetries. Two left-right asymmetries are examined from a wide range of languages, one morphological (the predominance of suffixation over prefixation), one phonological (the preference for anticipatory over perseverative phonology). Since phonological processes are ofte...
متن کاملPrivative Tone in Bantu
The purpose of this paper is to address the issue of “zeroing out” a tone in the above sense: When is an opposition properly analyzed as the presence vs. absence of a tone, rather than two different indications of tone, e.g. a + vs. of a tone feature?1 Although phonetic pitch (Fo) is scalar in nature, phonological (categorical) tone frequently has a privative character. The most frequent situat...
متن کاملsiderosis in Bantu
SYNOPSIS Twenty-seven specimens of human tissue, obtained by operation, were tested to evaluate the theory that iron uptake by tissues from serum is greater when transferrin is nearly completely saturated than when the degree of saturation is normal. Samples of each tissue were incubated in autologous serum so prepared that in one instance the transferrin was 50% saturated and in the second 90%...
