dome [E16th] Latin domus ‘house’ entered English directly as dome in the 16th century in the sense ‘a stately building’; it also passed through Italian duomo and French dôme to enter English for a second time as dome ‘a rounded vault’ in the mid 17th century. Domus is also found in domestic [LME] ‘relating to the house’ and in domicile [LME] ‘home’.
