Yo paḷāso paḷāsāyanā paḷāsāyitattaṃ paḷāsāhāro vivādaṭṭhānaṃ yugaggāho appaṭinissaggo—

That which is a quarrel, that which is quarrelling, and that which is quarrelsomeness, the way of quarrel, the point of dispute, the coming to fight, unrelenting—this is called quarrelling. A person in whom such quarrelling remains unremoved is said to be a quarrelsome person.
