Enliven

Verb

1. To give life or spirit to; to revive or animate.
2. To make more lively, cheerful or interesting.

   "The game was much enlivened when both teams scored within five minutes of each other."

3. ↑ The Oxford English Dictionary (2007) states that enliven was formed by the simultaneous prefixing of en- and suffixing of -en, which, by definition, constitutes circumfixation.
