>so, how is this different..

well, not to be flip about it, there are four unique rotes in W3 (more in OED), all from varying roots:

1. L. rotare
2. perhaps akin to Old Norse rauta
3. Middle English, rote, perhaps from L. rota [see 1]
4. rote from Middle English, from Old French, of Germanic origin; akin to Old High German hruozza, probably of Celtic origin; akin to Middle Irish crott; rota, rotta, rotte from Medieval L. rota, rotta, from Old French rote

the different senses are left as an exercise for the student. <g>
