Maybe from Proto-Indo-European *leh₂p- (“to shine”) and so cognate with Old Norse leiptr (“lightning”), Lithuanian liepsnà (“flame”), Ancient Greek λάμπω (lámpō, “to shine”), Lithuanian lópė (“light”), Latin limpidus (“bright”).
lāpa f (4th declension)
lāpa
The connection between 'talk' and 'quail' is that quails seem to talk a lot. The form corresponding to Sanskrit लाब (lāba, “quail”) would have merged with *lāpa (“talker”) in some eastern dialects.
