IPA: /ˈædɪkwəsi/
KK: /ˈædɪkwəsi/
The quality of being enough or satisfactory to meet a certain requirement or need.
The adequacy of the resources provided was questioned by the committee.
Adequacy is formed from "ad-" (meaning to or toward) and "aequus" (meaning equal or level). The word describes a state of being equal to or sufficient for a particular purpose.
Think of 'equal' ('aequus') and remember that 'adequacy' means being sufficient or equal to a need.
