"a small knot of women listened to his sermon"
"the bird had a knot of feathers forming a crest"
"the saw buckled when it hit a knot"
"their muscles stood out in knots"
"the old man's fists were two great gnarls"
"his stomach was in knots"
"She knotted her fingers"
"knot the shoelaces"
"a ravelled story"
