Sweetened Sweet is an adjective rather than a verb. Sweeten is a verb, and, as stated above, sweetened is its past tense. Another answer with additional information: Verbs in English have four forms: present tense, present participle, past tense, and past participle. You can always get it correct by substituting: Present tense: Today I sweeten. Present participle (sometimes called gerund): Now I am sweetening. Past tense: Yesterday I sweetened. Present or past participle: I have sweetened. Listen to yourself speak. If you speak correct English, it works for all verbs.
