leanly adv.
leanness n.

Synonyms: lean2, skinny, scrawny, lank, lanky, gaunt
These adjectives mean lacking excess flesh. Lean emphasizes absence of fat but usually suggests good health: The farmer fattened the lean cattle for market. Skinny and scrawny imply unattractive thinness, as from undernourishment: "His face and belly were so round, and his arms so skinny, that he looked like a dough ball with four sticks stuck into it" (John Green)."He [had] a long, scrawny neck that rose out of a very low collar" (Winston Churchill).
Lank describes one who is thin and tall, and lanky one who is thin, tall, and ungraceful: "He was ... exceedingly lank, with narrow shoulders" (Washington Irving).
The boy had developed into a lanky adolescent. Gaunt implies boniness and a haggard appearance; it may suggest illness or hardship: a white-haired pioneer, her face gaunt from overwork.
