secuplus

Sense 1 ultimately from sēmi- (“half”) and sēsqui- (“one and a half”): perhaps compare the sē̆- of sē̆lībra (“half-pound”), sēmodius (“half-pack”). Sense 2 ultimately from sex (“six”): perhaps compare the sē- of sēdecim, sēnus, sēmēnstris, sēvir, although the development of -ex- to -ē- was only phonetically regular before a voiced consonant. It is possible that some cases are simply misspellings by omission of a letter.
