Comments: Bsq does not tolerate two aspirates in the same word, usually keeping the last, so *elhi < *helhi = PEC *kwīlʡɨ 'hand'. Underlying *l is supported by the BZK and GIP allomorph el- and by the soft /r/ of erhi, eri,, though some forms have secondarily developed a trilled /r̄/ in composition: GIP erraztun, LAB erreztun 'ring' (Michelena 1961: 331). Comparison of Bsq *elhi with PEC *kwīlʡɨ 'hand' is also possible, though phonetically somewhat less probable.
