Meaning & usage
Combining form used to form prefixed verbs with the approximate meaning "to fill".
Where this word comes from
Exists only as a bound morpheme in prefixed verbs, where it continues Proto-Italic *plēō, perhaps—according to De Vaan—from a root aorist *pléh₁-t, from Proto-Indo-European *pleh₁- (“to fill”). The perfect passive participle plētus may have replaced earlier *plātus, from *pl̥h₁tós. However, the pre-form of the participle is alternatively reconstructed as *pleh₁tós. For cognates, compare Russian -по́лнить (-pólnitʹ), a cognate with the same meaning that likewise does not occur uncompounded.
