Lexical diffusion
Encyclopedia
In historical linguistics
, lexical diffusion is both a phenomenon and a theory. The phenomenon is that by which a phoneme is modified in a subset of the lexicon, and spreads gradually to other lexical items. For example, in English
, /uː/ has changed to /ʊ/ in good and hood but not in food; some dialects have it in hoof and roof but others do not; in flood and blood it happened early enough that the words were affected by the change of /ʊ/ to /ʌ/, which is now no longer productive
.
The related theory, proposed by William Wang in 1969 is that all sound changes originate in a single word or a small group of words and then spread to other words with a similar phonological make-up, but may not spread to all words in which they potentially could apply. The theory of lexical diffusion stands in contrast to the Neogrammarian hypothesis that a given sound change applies simultaneously to all words in which its context is found.
William Labov
, in Principles of Linguistic Change, takes the position that there are two types of sound changes: regular sound change (respecting the Neogrammarian hypothesis) and lexical diffusion. Labov lists a typology, according to which certain phenomena are typically or exclusively regular (example, vowel quality changes), while others (example, metathesis, or vowel shortening) tend to follow a lexical diffusion pattern.
Paul Kiparsky
, in the Handbook of Phonology (Goldsmith editor), argues that under a proper definition of analogy as optimization, lexical diffusion is not a type of sound change. Instead, Kiparsky claims it is similar to leveling
, in that it is a non-proportional type of analogy.

Productivity (linguistics)
In linguistics, productivity is the degree to which native speakers use a particular grammatical process, especially in word formation. Since use to produce novel structures is the clearest proof of usage of a grammatical process, the evidence most often appealed to as establishing productivity is...

Morphological leveling
In linguistics, morphological leveling is the generalization of an inflection across a paradigm or between words. For example, the extension of the form is to persons such as I is and they is in some dialects of English is leveling, by analogy with a more frequent form, as is the reanalysis of...
