Of or pertaining to shunning the end (of anything).
From Latin fini-s end + fug-a flight + -al
1883 A. Tollemache in Jrnl. Educ. 1 Sept. "In modern as well as in ancient times, the finifugal tendencyis apparent."
Whenever anyone ever accused me of never being committed or never finishing what I started, rather than shrug or get defensive, I can simply look over my many unfinished books, games, and other hobbies and tell them I am simply finifugal!
