the trace of a point whose direction of motion changes
unable to see
a line on a graph representing data
people who have severe visual impairments, considered as a group
unable or unwilling to perceive or understand
not based on reason or evidence
turn sharply; change direction abruptly
make blind by putting the eyes out
render unable to see
a pitch of a baseball that is thrown with spin so that its path curves as it approaches the batter
