Ma'anar ƙamus na kalmar "rashin hankali" shine ingancin rashin tasiri ko rashin aiki, rashin himma ko ƙarfin hali, ko rashin kulawa da rashin amfani. Sau da yawa ana ganin marar taki a matsayin malalaci, marar dogaro, da rashin azama ko manufa. Kalmar kuma tana iya nufin rashin iyawa ko tasiri wajen cimma burin ko kammala ayyuka.
