A 1920s clipping of refrigerator, with a -d- inserted by analogy with bridge and ridge.
A refrigerator; an appliance for keeping food and drink cold.
An informal clipping of 'refrigerator,' with the spelling altered from 'frig' to 'fridge' by analogy with words like bridge, ridge, and judge. The Frigidaire brand (trademarked 1919) may have influenced the popularity of the short form but did not originate it. Key roots: *srīg- (Proto-Indo-European: "cold, frost").
