potion: [13] The Indo-European base *pō-, *pī- ‘drink’ has provided the verb for ‘drink’ in most modern European languages, apart from the Germanic ones: French boire, for instance, Russian pit’, and Welsh yfed all come from it. Amongst it Latin descendants were the nouns pōtiō ‘drink’, source of English potion (and also poison) and pōtus ‘drink’, the probable ancestor of English pot, and the verb pōtāre ‘drink’, from which English gets potable [16].
