What does chubbiness mean?
Chubbiness is the quality of being chubby — that is, pleasantly plump, rounded, and full in shape, whether describing a baby's arms, a child's cheeks, or the well-fed figure of a pet. It is formed from the adjective 'chubby' by adding the suffix '-ness', which turns qualities into nouns. The word carries a warm, affectionate connotation far more often than a critical one: chubbiness evokes health, youth, and cuteness, particularly in babies and young children. In formal medical contexts, terms like 'adiposity' or 'overweight' would be preferred instead. Because comments about body size can be sensitive, 'chubbiness' is best used playfully or admiringly — about infants, animals, or oneself — rather than as an unsolicited description of another adult's figure. Its enduring charm lies in its gentle, rounded sound, which seems to mimic the very fullness it describes.

'Chubby' may come from the chub, a plump freshwater fish — so when you call someone chubby-cheeked, you're comparing them to a fish.

Etymology of chubbiness
Chubbiness derives from the adjective 'chubby', which appeared in English in the late 16th or early 17th century. The most commonly cited origin is the noun 'chub', a plump-bodied freshwater fish of the cyprinid family, with 'chubby' originally meaning 'chub-like' before shifting to describe human plumpness. An alternative theory links it to an Old French word for a head or lump, but the derivation from the fish's name is the one most lexicographers favor. The suffix '-ness' is a native Germanic ending used to form abstract nouns of state or quality from adjectives.
