    Since the meanings 'sea' and 'moisture, liquid' sometimes interchange (cf., for example, the reflexes of PEC *ɦwmǟɦwā), it seems tempting to compare also Arch. hoIlo-t:u- 'liquid' (and perhaps as an old dialectal variant, with another frequent semantic change 'liquid -> green' - Arch. oIlow-t:u- 'green'). There are no other probable hypotheses about the origin of these Archi words.
