ETYMOLOGY
from Latin lepidus (pleasant; charming; witty)
EXAMPLE
“… In his daily walks into the fields, nothing pleased him so much as the chat of some well-informed fellow of the college, who would join him in quoting ‘sweet extemporaries’ from Gelius or Macrobius, or ‘in guessing at the lepid derivation’ of English words. To those who were of his own standing, it is to be feared that his conceit and pedantry proved in many cases offensive. …”
