"Kinase" has the same root as "kinetics", which is from the Greek word meaning 
"to move"...I forgot the exact word (still waking up), but it's something like 
"kineto", meaning "I move". Sticking -ase on the end...well I don't know where 
we get that from, but we use it to signify an enzyme, so I suppose literally 
it's "enzyme that promotes motion". Presumably because the phosphate group is 
moved from one place to another? Or because phosphate transfers are associated 
with motility in cells? As usual, raises more questions than answers.
