COMMENT: In PL and Khin. there occurred a secondary metathesis (we should expect a form like PL *Holƛ̣:) - probably to avoid a cluster of two laterals. Otherwise the correspondences are regular. PWC has a prefixed *b- (as in many other cases). See Abdokov 1983, 81 (where the root is mixed up with *rĕmƛ̣e 'cubit' q.v.)
