1.5 Quantity is the turn used against quality, involves durational difference whereas the latter involves mostly articulatory variations. Quantity in Tamil Phonetics functions both as linear as well as suprasegmental. 2 Prediction Both the vocalic and non-vocalic sounds have the quantity as well as the quality differences. The vocalic sounds when having quantitative difference in form, behave functionally as a single unit and only when they have qualitative difference in form, behave functionally as sequence. The non-vocalic sounds viz., approximants, obstruants and sonorants have quantitative difference in form but in function they behave as sequence. 2.4 Vowel quality could be classified into two types viz., prolongation with same vocal configuration and prolongation with gradual changing from open to narrow approximation. The former is a long vowel and the latter is the sequence of a vowel and the corresponding approximant i. e., if the nucleus of the sequence is a back vowel the accompanying one is the corresponding back rounded approximant and if it is a front vowel the accompanying one is the front un rounded approximant.
