Pamplemousses is a plural noun (often used in place names) derived from the French for 'grapefruit' (painfully close to ‘pink grapefruit’ in English usage when referring to a locale). In contexts, it can denote a district or unit within a place, typically with a refined or historical connotation. The pronunciation tends to mirror French-influenced stress and vowel quality, even in English discourse.
