Skilled ASL signers often do an abbreviated version of this sign. In
the abbreviated version, the right hand doesn't actually circle the left
hand. It simply makes a very small circle above the left hand then comes
to rest on top of the left hand.
LAST YEAR, (the recent year)
Sideways view of "recent year"
(or "one year ago")
"two years from now" "in two years"
For this version, the left hand stays mostly stationary and the right hand
comes down and whacks it. The right hand changes from a fist to an index
as it moves down to strike the left fist.
