Etymology

The word "sunny" derives from Old English sunne (the sun) combined with the adjectival suffix -y, which originates from Old English -ig, meaning "having the quality of." The suffix -y is widely used in English to form adjectives indicating abundance or resemblance (e.g., "cloudy," "windy"). Over time, "sunny" evolved from its literal sense of "filled with sunlight" to also describe a cheerful demeanor, metaphorically linking brightness to mood.
