pustule: [14] Despite the fact that pustules contain pus, there is no etymological connection between the two words. Pustule comes via Old French pustule from Latin pustula ‘blister’. This was a derivative of a prehistoric Indo-European base *pu- signifying ‘blow’, so etymologically it means ‘inflated area’.
pustule (n.)
late 14c., from Old French pustule (13c.) and directly from Latin pustula "blister, pimple," from PIE imitative root *pu- (1) "blow, swell," on notion of "inflated area" (cognates: Sanskrit pupphusah "lung," Greek physa "breath, blast, wind, bubble," Lithuanian puciu "to blow, swell," Old Church Slavonic puchati "to blow"). Compare emphysema. Related: Pustulant; pustular.
