Past tense of luck: to get something by chance or good fortune, usually used as 'lucked out' or 'lucked into'.
From Middle English and Middle Dutch 'luck' or 'luc', origin uncertain but possibly from Germanic roots meaning to happen or occur.
Interestingly, 'luck' wasn't considered a serious concept in ancient philosophy—fortune existed, but they thought character determined fate; the modern idea that 'luck' is real and measurable only developed alongside probability mathematics in the 1600s.
