I heard it tonight and I believe I’ve heard it before but not often. Tonight on TV (MSNBC Last Word with Lawrence O’Donell) was the long discussion about truth vs-à-vis things like the size of the crowd at the inauguration or the numbers of fraud voters in the last US election. “When the truth becomes fungible.”
OED Etymology: < medieval Latin fungibilis (‘res fungibiles’ Du Cange), < fungī (with sense as in fungi vice, to take the place, fulfil the office of).
The adjective belongs to Civil Law and to the general theory of Jurisprudence; the noun is in addition a current term of the law of Scotland.
: readily changeable to adapt to new situations : flexible <Managers typically use more than a hundred different lineups over the course of the season. Batting orders are so fungible that few players last long in one spot. — Tom Verducci>
