俱舍論記 9.28

9.28

「謂唯香氣至好香為食」者，健達縛是短音中呼，若長聲中喚應言健達頞縛。其健達名香，是字緣。頞縛，是字界，或目尋義、或目食義。尋謂尋香，食謂食香。以健達助頞縛，即名健達頞縛。此中依短聲中呼，略去頞字，但言健達縛。若長聲喚達，即亦攝頞；若短聲喚達，即不收頞。雖短聲喚達，亦無有過。引聲明中體例來證，如設建途及羯建途，竝是短聲中喚建；若以長聲，應言設建頞途、羯建頞途。設建、羯建竝是字緣，頞途是字界。長聲、短聲類前應解。依聲明論，有字界、字緣，其字界有字緣來助，即有種種義出。如米、麵等鹽等助時，即有種種味出。餘文可知。

[On the phrase] 'meaning that they take only odor as food... to feed on fine odor': gandharva is pronounced with a short vowel; if called with a long vowel, it should be pronounced gandhārvā. Gandha means odor, which is the affix (pratyaya). Arva is the verbal root (dhātu), signifying either seeking or eating. Seeking means seeking odor; eating means eating odor. When gandha qualifies arva, it becomes gandhārva. Here, based on pronunciation with a short vowel, the syllable a is omitted, and it is simply called gandharva. If dha is called with a long vowel, it also subsumes a; if dha is called with a short vowel, it does not include a. Even though dha is called with a short vowel, there is no fault. Citing grammatical rules as evidence: for instance, śakaṃdhu and karkaṃdhu both pronounce kaṃ with a short vowel; if with a long vowel, they should be śakāndhu and karkāndhu. Śakaṃ and karkaṃ are both affixes, and andhu is the verbal root. Long vowels and short vowels should be understood analogous to the previous [explanation]. According to grammar treatises (Vyākaraṇa), there are verbal roots and affixes; when a verbal root is modified by an affix, various meanings are produced. Just as when rice, flour, and the like are modified by salt and the like, various flavors are produced. The rest of the text is self-evident.
