Those languages located in mainland Southeast Asia are most likely to share features in common with Sinitic languages, such as monosyllabicity
and isolating word formation characteristics, potentially complex lexical tone systems, serial verb constructions, aspectual and mood contrasts rather than tense oppositions, a general absence of inflectional morphology, and rudimentary relational marking.
Generalizations about processes (e.g., deletion, epenthesis, morpheme coalescence) and also minimality/maximality constraints (e.g., the strong preference for monosyllabicity
) may be made at the level of the phonological word in sign languages.
Monosyllabicity: Ideally, a phonological word consists only of one syllable
Besides, the "tendency for monosyllabicity" (Brentari 1998: 6) or "monosyllabic conspiracy", as Sandler and Lillo-Martin (2006: 228-231) call it, will be discussed.
Thus, a single syllable results, a highly desirable output, because it not only keeps within the upper boundary of PW D = 1 [greater than or equal to] 2[??], but even monosyllabicity is achieved (see Emmorey 2002: 20).
what was originally two signs, each with its own movement, has become a cliticized form with a single movement." Since "..., a single movement is considered by many researchers to define a syllable, and has been argued to be the optimal prosodic form of a word" (2006: 7, see also Sandler 1999), the above example can be considered as a particularly clear example that the syntactic process of cliticization operates within the prosodic domain of the phonological word and results in an optimal form, in the sense of monosyllabicity. Sandler adduces further evidence from mouthing that the resulting clitic group forms a single prosodic constituent.
While coalescence relates to the monosyllabicity constraint, assimilation relates to the selected finger constraint.
Therefore it is interesting to see through what mechanisms such overshooting is reduced and the limit of two syllables or even monosyllabicity is retained.
