From Proto-Indo-European *pleh₂-u-d- (“to clap the hands”), from *pleh₂-u-h₂- (“palm of the hand”), from *pleh₂- (“flat”). Related to plautus (“trod flat”); see there for more cognates.
Older theories derived the word from Proto-Indo-European *pleh₂k-, the same root of Latin plēctō (“to braid”), plangō (“to strike”), plaga (“plague, wound”) and Ancient Greek πλήσσω (plḗssō, “to strike”). (Can this etymology be sourced?)
plaudō (present infinitive plaudere, perfect active plausī, supine plausum); third conjugation
