1) put the cursor on the m
2) to yank to the first r (the one in the middle of "cursor"):
yfr
2a) or to yank to the second r (at the end of "cursor")
y3e
(i.e. "yank to the end of the 3rd word") or
vfr;y
see
:help f
:help e
:help ;

Or you could set a Visual mode highlight to whatever you wanted to yank,
and just hit y (as in the last example above)

Or to yank just the word "cursor" you could place the cursor anywhere on
it, and then do
yiw
i.e. "yank inner word", see :help iw

It can: the y command (in Normal mode) expects a motion to tell it how
far to yank. There are a lot of possible motions, see :help motion.txt
