citron
Synonym discussion
Sense: noun/1
Lemon, pomelo, grapefruit, and citron are all citrus fruits, but they serve different uses in the kitchen. A citron is larger than a lemon and has a noticeably thicker, bumpier rind with almost no juicy segments inside — it is never eaten fresh like a grapefruit. Lemons are valued for their tart juice and zest; pomelos and grapefruits are eaten for their sweet-tart flesh. Citrons, by contrast, are grown almost solely for their thick, aromatic peel, which is candied or preserved. For example: 'She added candied citron peel to the fruitcake, not lemon zest.' 'Unlike a grapefruit, a citron has no segments to scoop out for breakfast.'

Etymology
Citron entered English from French citron, which came from Latin citrus, the name for the citron tree. The fruit was brought to Europe from its native region in South Asia and Southeast Asia, and its name spread through Mediterranean languages alongside the fruit itself.
