In a way that deserves contempt or scorn; in a shameful or despicable manner.
From 'contemptible' (capable of being despised) plus the adverbial suffix '-ly.' The adjective derives from Latin 'contemptibilis.'
This adverb is perfectly grammatical but sounds almost Shakespearean—modern speakers prefer 'shamefully' or 'despicably' instead, making this a word that feels slightly too formal for everyday use.
