disposition Look up disposition at Dictionary.com
late 14c., "ordering, management," also "tendency of mind," from Fr. disposition (12c.), from L. dispositionem (nom. dispositio), noun of action from dispositus, pp. of disponere "to set in different places," from dis- + ponere "to place" (see position). Associated in O.Fr. with dispose and thus in English. References to "temperament" are from astrological use of the word for "position of a planet as a determining influence."
