Sense: adjective/2
'Plump' is a gentle word for someone who is a little fat in a soft, rounded way. 'Chubby' is even warmer and is often used for babies or young children; with adults, it can sound playful. 'Fat' is the plainest and strongest term, so it may sound rude unless the speaker uses it neutrally about themselves. 'Stout' is older and more formal, and it often suggests a solid older adult rather than a child. 'Round' is milder and less exact, because it points to shape more than body fat. Compare: 'The baby has plump cheeks' sounds affectionate, while 'The baby is fat' sounds much harsher. 'Her uncle is stout' suggests a solid build; 'Her uncle is plump' suggests soft fullness.
Etymology
English took 'plump' from words in Middle Dutch and related Germanic varieties that meant something like 'blunt' or 'heavy-looking'. In late Middle English, it first had that rougher idea. Over time, the meaning shifted toward a more positive picture of soft, rounded fullness, probably helped by its sound similarity to 'plum'. The verb grew naturally from the adjective: if you plump a pillow, you make it look fuller and softer again.
