This episode delves into words with double meanings. From words with contradictory meanings, to those that have had their meanings change over decades and centuries. To 'dust' can mean to wipe fine particles away, or to sprinkle them, and 'sanction' can mean to allow or to restrict. Just like the word 'sick', the word 'bad' can, in some contexts, mean good. 'Nice' used to mean ignorant and 'awful' used to mean inspiring. Listen on for the etymologies behind these words of contradicting meanings.
