As today is St Patrick’s Day, I thought I’d look into the origins of the name Patrick.
Patrick comes from the Latin name Patricius, which comes from the word patricius (patrician, noble), from patrēs cōnscrīptī (Roman senators, or literally “enlisted fathers”) [source].
patrēs is the plural of pater (father, head of household, parent, forefather, priest), which comes from the Proto-Italic *patēr (father), from the Proto-Indo-European *ph₂tḗr (father), from *peh₂- (to protect, shepherd) and *-tḗr (agent suffix) [source].
Another word that comes from pater is patronus, which in the magical world of Harry Potter is a spirit guardian that can be summoned with the charm Expecto Patronum [source]. This is genunine Latin and means “I await my protector” [source].
cōnscrīptī is the plural of cōnscrīptus (senator, counsel(l)or; enrolled, enlisted, composed), which comes from conscrībō (I enroll, enlist, draw up, compose), from con- (with), and scrībō (I write) [source].
The English word conscript (One who is compulsorily enrolled, often into a military service) comes from the same Latin root [source].
