It is unclear precisely how PWMP *pagu and *paRa ‘storage shelf; attic (?)’ differed in meaning. The former may have referred to a loft or attic near the roof and the latter exclusively to a shelf or system of shelves over the hearth, but reflexes of *paRa so often include the meaning ‘loft, attic, ceiling’ that the semantic distinction between the two has been considerably blurred.
