desultory: [16] Latin dēsultor designated a circus trick-rider who jumped from the back of one horse to another while they were galloping along (it was a derivative of dēsilīre, a compound verb formed from dē- ‘down’ and salīre ‘jump’, source of or related to English assail, assault, insult, salacious, salient, and sally). From it was derived an adjective dēsultōrius ‘jumping from one thing to another like a dēsultor’, hence ‘superficial’, and eventually ‘unmethodical, irregular’, the sense which survives in English.
