adverb (indeclinable)
Analysis. sabba (all, every) + -so (ablative suffix, from all/every direction). The suffix -so derives from Proto-Indo-European *-smo, cognate with Sanskrit -śas and the ablative marker -s. The compound means literally 'from all' or 'in all manner'.
Etymology. sabba (all) is a Proto-Indo-European word cognate with Latin totus and English total through Indo-European *swepo- (one's own, whole). The ablative suffix -so carries the spatial sense 'from, away from'; spatial prefixes and case endings preserve their concrete imagery even in adverbial formations.
