Plural of ingle: a fireplace or open fire, especially one with a cozy corner.
From Scottish Gaelic 'aingeal' (fire), entering English in the 1500s through Scottish usage. Related to Gaelic and Irish words for fire or burning.
An 'ingle nook' was the coziest spot in medieval homes—people would sit by the fire and that architectural feature actually influenced modern furniture design, including the concept of 'cozy corners.'
