hereditary: [16] Latin hērēs ‘heir’ (a relative of Greek khéra ‘widow’ and Sanskrit hā- ‘leave, lose’) has been quite a prolific source of English words. For one thing there is heir [13] itself, acquired via Old French heir. And then there are all the derivatives of the Latin stem form hērēd-, including hereditament [15], hereditary, heredity [16], and, via the late Latin verb hērēditāre, heritage [13] and inherit [14].
