Mnemonic:Since   an  APTitude    is  a   skill,  to  be  INEPT   is  to  lack    skill.IN  (not)   +   APT (skill) =   INEPT- Joshua    is  an  inept   dancer; he  is  as  likely  to  stomp   on  his partner’s   foot    as  he  is  to  step
on it. - Julia’s inept attempt at humor drew only groans from the audience.
 
To be inept is to be characterized by ineptitude, which is the opposite of aptitude.
- The   woodworking class’s ineptitude  was broad   and deep;   there   was little  that    they    were
able to do and nothing that they were able to do well. 
The opposite of inept is adept (uh DEPT).
