Synonym discussion
Sense: adverb/1
All four words describe doing something with real effort, but they highlight different things. `Actively` is the most neutral and common: it simply means you are doing real things, not just watching or waiting — `actively looking for work`. `Energetically` focuses on the physical or mental vigour someone brings, often to a single task — `she danced energetically all night`. `Vigorously` is stronger again, suggesting forceful, determined effort, and is common with verbs like `defend`, `deny`, or `oppose` — `the minister vigorously denied the claims`. `Proactively` is the most formal and business-flavoured; it stresses acting before a problem appears, not just acting at all — `the team proactively warned customers about the delay`. When in doubt in everyday writing, choose `actively`.

Etymology
Formed in English by adding the adverb-making suffix `-ly` to the adjective `active`. `Active` itself came into English in the 14th century from Old French `actif`, which traced back to Latin `activus`, from `agere` meaning `to do` or `to drive`. So at its root, `actively` literally means `in a doing way`.
