senary

senary (SEN-uh-ree) - adj., of, based on, or relating to the number six; having six parts; of the sixth rank.


Sixth! Also used for the base-6 number system. Adopted in 1661 from Latin sēnārius, consisting of six each, from sēnī, six each (from sex, six) + the adjectival ending -ārius (from whence the English adjectival suffix -ary).
