In some models of phonology as well as morphophonology in the field of linguistics, the underlying representation (UR) or underlying form (UF) of a word or morpheme is the abstract form that a word or morpheme is postulated to have before any phonological rules have been applied to it. [1][2] In contrast, a surface representation is the ...
Optimality theory (frequently abbreviated OT) is a linguistic model proposing that the observed forms of language arise from the optimal satisfaction of conflicting constraints. OT differs from other approaches to phonological analysis, which typically use rules rather than constraints. However, phonological models of representation, such as ...
In general, phonological rules start with the underlying representation of a sound (the phoneme that is stored in the speaker's mind) and yield the final surface form, or what the speaker actually pronounces. [3] When an underlying form has multiple surface forms, this is often referred to as allophony.
There are at least two levels of representation: underlying representation and surface phonetic representation. Ordered phonological rules govern how underlying representation is transformed into the actual pronunciation (the so-called surface form). An important consequence of the influence SPE had on phonological theory was the downplaying of ...
Autosegmental phonology is a framework of phonological analysis proposed by John Goldsmith in his PhD thesis in 1976 at the Massachusetts Institute of Technology (MIT).. As a theory of phonological representation, autosegmental phonology developed a formal account of ideas that had been sketched in earlier work by several linguists, notably Bernard Bloch (1948), Charles Hockett (1955) and J. R ...
A simplified procedure for determining whether two sounds represent the same or different phonemes. A phoneme is a sound or a group of different sounds perceived to have the same function by speakers of the language or dialect in question. An example is the English phoneme /k/, which occurs in words such as cat, kit, scat, skit.
In the field of linguistics, specifically in syntax, phonetic form (PF), also known as phonological form or the articulatory-perceptual (A-P) system, is a certain level of mental representation of a linguistic expression, derived from surface structure, and related to Logical Form. Phonetic form is the level of representation wherein ...
English orthography does not always provide an underlying representation; sometimes it provides an intermediate representation between the underlying form and the surface pronunciation. This is the case with the spelling of the regular plural morpheme, which is written as either - s (as in tat, tats and hat, hats ) or - es (as in glass, glasses ).
