The term "liven" is derived from the adjective "live" (from Middle English "liven" or "leven") which means "having life" or "full of energy". It can also be traced back to the Old English word "līf", meaning "life". The verb "to liven" was formed by adding the suffix "-en" to the adjective, which is commonly used in English to create verbs from adjectives. Therefore, "liven" means "to make something lively or full of life".
The word "up" in this context is an adverbial particle that is added to phrasal verbs to modify or intensify their meaning. In this case, it adds the sense of increasing or enhancing the liveliness.
