Admirable: This is the antithesis of “detestable,” something or someone that inspires admiration or acceptance.
Separate: This term means something or someone that exists independently or is isolated from others; it bears no relationship to hatred or loathing.
Conscionable: This term defines something that is right or reasonable. It is the opposite of unconscionable.
