aspartame (n.) Look up aspartame at Dictionary.com
commercial name of an artificial sweetener, 1973, from aspartic acid (1836), formed irregularly from asparagine (1813, earlier in French), a crystalline compound found in asparagus, beet-root, etc., which was named from asparagus + chemical suffix -ine (2). The -ame is perhaps because aspartamine is an amide.
