ingle (n.1)

"fireplace," c. 1500, from Scottish, usually said to be from Gaelic aingeal "fire, light" ("but there are difficulties" [OED]), a word of uncertain origin. The vogue for Scottish poetry in late 18c. introduced ingleside "fireside" (1747) and ingle-nook "corner by the fire" (1773) to literary English.

"boy favorite, catamite," 1590s, of uncertain origin.
