anxious
adj.
1620s, from Latin anxius "solicitous, uneasy, troubled in mind" (also "causing anxiety, troublesome"), from angere, anguere "choke, squeeze," figuratively "torment, cause distress" (see anger, v.). The same image is in Serbo-Croatian tjeskoba "anxiety," literally "tightness, narrowness." Related: Anxiously; anxiousness.
