Today's four words move from a tiny subatomic particle, to someone who opposes you, to a sudden involuntary muscle contraction, to something that obstructs or a child's building toy.

One word names an elementary particle smaller than a proton; another is a rival or foe; a third is a sudden, painful muscle cramp; the last describes obstructing something, or a simple wooden cube kids stack.

Picture a physicist studying particles smaller than an atom, a sworn rival in a story, a sudden charley horse in your leg, and a toddler stacking colorful cubes.

Near-matches to help narrow it down: think "particle" for the first, "foe" for the second, "cramp" for the third, and "obstruct" for the fourth.

Starting letters today: Q, E, S, B.
