The word “unable” is an adjective that describes a state of lacking the power, skill, opportunity, or means to do something. It essentially means “not able.” It indicates a deficiency or limitation, preventing someone from performing a specific action or task.
Understanding its definition is the first step in finding its antonyms.

The word is versatile and applicable in numerous situations where capability is lacking.
Structural Breakdown of ‘Unable’
The word “unable” is formed by adding the prefix “un-” to the adjective “able.” The prefix “un-” is a negating prefix, meaning it reverses the meaning of the word it’s attached to. Therefore, “unable” literally means “not able.”
Root Word: Able (adjective meaning having the power, skill, means, or opportunity to do something)
Prefix: Un- (a negative prefix)
Formation: un- + able = unable
Understanding the structure of “unable” helps in recognizing other words formed with the “un-” prefix and grasping their meanings more easily. Recognizing this pattern is useful for deducing the meaning of unfamiliar words in the English language.
This knowledge can significantly enhance vocabulary acquisition and reading comprehension.
