the word 'sweetened' is built upon the old english root 'swēte', which itself descends from the proto-germanic 'swōtijaz' and ultimately the proto-indo-european 'swéh₂dus', meaning pleasant or sweet. the addition of the old english verbal suffix '-en' transforms the adjective into the verb 'sweeten', meaning 'to make sweet'. the final '-ed' suffix marks the word as a past participle, creating an adjective that describes something which has undergone the process of being made sweet. thus, the modern term logically combines the concept of a pleasant taste with the action of causing that state and its resultant condition.
