et•y•mol•o•gy:

Latin verb trepaliare: 

to torture; it derived from trepalium, a name for an instrument of torture.

Trepaliare developed into medieval French travailler: 

to torture; to suffer or labor.

Middle English transformed the French term into travailed: 

to torture, to suffer or labor; getting from place to place in the Middle Ages had been an exhausting effort, so medieval speakers of English applied travailed  to making a trip.
