Gamesome is an adjective that means playful and happy.
Our word of the day combines the word ‘game’ a word of Old English origin with the suffix S-O-M-E, which usually means ‘characterized by being.’ So a tiresome person is characterized by being tired. Similarly, a gamesome person is characterized by being eager and willing.
For example: Charlotte didn’t seem like herself today. She is usually in a gamesome mood, but today she seems morose and moody.
