IPA: /vəˈdʒɪlɪti/
KK: /vəˈdʒɪlɪti/
The ability of an organism or species to move around or spread in its environment.
The vagility of certain bird species allows them to migrate long distances each year.
Vagility is derived from "vag-" (from Latin "vagari", meaning to wander) and the suffix "-ility" (meaning the quality of being). The word "vagility" refers to the quality of being able to wander or move freely.
Think of 'wandering' ('vagari') to remember that 'vagility' means the ability to move freely.
