IPA: //suːˈkræloʊs//
KK: /sʊˈkrɑːloʊs/
A type of sweetener that is much sweeter than sugar but has no calories, often used in food and drinks.
Many diet sodas use sucralose as a sugar substitute to reduce calories.
Sucralose is formed from "sucrose" (from Latin "sucrosus", meaning sugary) and the suffix "-lose" (indicating a sugar or carbohydrate). The word refers to a sugar derivative that is modified to be sweeter than sucrose while having fewer calories.
Think of 'sucrose' which means sugary, and remember that 'sucralose' is a sweetener derived from sugar.
