Capable is capable of carrying out tasks, capable, and agile. The word ability has the same meaning as dexterity. Ability or dexterity is the ability to do something quickly and correctly. A person who can do quickly but wrong cannot be said to be capable. Spencer and Spencer in Hamzah Uno define ability as a salient characteristic of a person related to effective and/or superior performance in a job or situation. Poerwadar asked for another opinion about ability, namely capable, power (able, able) to do something, while ability means to save, strength. Another opinion was expressed by Nurhasanah, that being able means (able, able) to do something, while it means ability, ability. Likewise, if someone does something right but slowly, it can also be said to be able. A person who is capable in a field does not hesitate to do the job, as if he has never thought about how to carry it out, there are no more obstacles that hinder him.
