s, they were at times conflated, e.g., Tocharian B ymiye (and also yamo*?). (When used as agent nouns or as adjectives this class shows replacement of the nominative singular by the accusative.) There are other nouns of this class in both Tocharian languages which show Back Vowel Umlaut and manifest no trace of original palatalization of the root final consonant, e.g., B sopiye* "net," olyiye* "ship," molyiye* "struggle" (both with superficial palatalization of /1/ before /i/, see Adams, forthcoming), or B proskiye [ A praskil " fear." It is possible that such nouns show a Proto-Indo-European *-uHen-. The loss of laryngeals left *-iHenand *-uH nas *iyenand *uwen-. At that time *-iyencould be segmented as *-i-yenrather than *-iy-enand such an analysis would lead to the replacement of *-uwenby *-uyen-. The latter develops regularly to [AB] -ibut with no palatalization of the preceding consonant and backing and rounding of any susceptible preceding vowel. A trace of the original u(H)stem may be seen in B prari "finger" (from *p(e)roruyen< *p(e)riruHen-) but plural nominative praroi (from *p(e)rrruHnes). Tocharian A shows this word without a n-extension, i.e., sg. prar (< *p(e)riru), pl. praru* (< *p(e)rorwd). As an adjective we have B arkwi [A arkil "white," pl. nom. arkwimn (for *arkwih), pl. acc. arkwindarn, all from *arguyen(< *arguHen-, cf. Latin argatus "clear, significant") with the accusative singular again as a nominative. (Proto-Indo-European *u gives Tocharian B /o/ when subject to Back Vowel Umlaut, /wd/ when absolutely initial or after /k/, and /a/ elsewhere.) 8 Except in adjective stems in -r-, the -m is (secondarily ?) lost. 9 The final -e (in Tocharian B) from Proto-Indo-European *-oH is surprising.

The evidence is most explicit for class (2) which includes several adjectives in Tocharian B and one or two in Tocharian Aall based on Proto-IndoEuropean *-mon-/-men-, e.g., Tocharian B klyomo [A klyomj "noble." In Tocharian B the vowel *-6of the nominative singular has been extended throughout the masculine paradigm. In Tocharian A, though the declension has been assimilated to that of the ntstems, we see traces of Proto-Indo-European *-ein, for instance, the acc. sg. m. klyomant. The feminine in both languages is also based on ProtoIndo-European *-men-, with the addition of *-ain Tocharian A and of *-yain B, e.g., B klyomfia, A klyomi .M. Class (5) adjectives, however, appear to have been the productive "weak" declension in Proto-Tocharian and, insofar as they survive, they have become assimilated to their thematic (i.e., "strong") counterparts. The usual result of this conflation of strong and weak for the masculine adjective was the retention of the strong nominative singular (i.e., no preceding palatalization) and the weak accusative singular (i.e., with preceding palatalization and, in Tocharian B, the extension of the vowel -e[from either PIE *-eor *-o-] at the expense of-a[from PIE *-e-] ). Thus, in the singular, we have the following developments: SINGULAR Proto-Tocharian Toch. Toch.
