Inexcusable vs. Unexcusable – Which is Correct?
The correct spelling is inexcusable. The term “unexcusable” is a common misspelling and is not recognized in standard English dictionaries. Always use “inexcusable” to describe something that cannot be justified or forgiven, ensuring clarity and grammatical accuracy in your writing.
Inexcusable or Unexcusable – Which is Correct?
When faced with the choice between “inexcusable” and “unexcusable,” the definitive answer is inexcusable. The word “unexcusable” is a widespread misspelling and does not exist in standard English. The confusion often stems from the common use of the prefix “un-” to denote negation (e.g., “unhappy,” “untrue”). However, for the root word “excusable,” the correct negative prefix is “in-.”
The root cause of this error is often phonetic confusion or a general tendency to overapply the “un-” prefix. While “un-” and “in-” both serve to negate, their usage is largely determined by the specific root word and its historical linguistic development. In the case of “excusable,” the established and correct form is “inexcusable.”

How to Use Inexcusable
The adjective “inexcusable” is used to describe an action, behavior, or situation that is so wrong, bad, or severe that it cannot be pardoned, justified, or forgiven. It conveys a strong sense of disapproval and implies a violation of moral, ethical, or practical standards. It is often used in formal and serious contexts, emphasizing the gravity of the transgression.
Example 1: Leaving the children unsupervised, even for a moment, was an inexcusable lapse in judgment.

What are the different forms of Inexcusable?
“Inexcusable” is primarily used as an adjective. While it doesn’t have different tenses or pluralizations like verbs or nouns, it can be modified by adverbs to intensify or qualify its meaning (e.g., “truly inexcusable,” “completely inexcusable”). The corresponding noun form is “inexcusability,” referring to the quality of being inexcusable.
Etymology of the word Inexcusable
The word “inexcusable” has its roots in Latin. It derives from the Latin prefix “in-” (meaning “not” or “opposite of”) combined with “excusabilis,” which means “that may be excused.” “Excusabilis” itself comes from “excusare” (“to excuse, to free from a charge”), formed from “ex-” (“out of, from”) and “causa” (“cause, reason”). Thus, “inexcusable” literally means “not able to be excused or justified by reason.” It entered English in the late 16th century.
Related Concepts
Understanding the prefixes “in-” and “un-” is key to avoiding misspellings like “unexcusable.” Both prefixes serve to negate or reverse the meaning of a word, but they are not interchangeable. Generally, “un-” is more common and can be applied to a wider range of words, especially adjectives formed from participles (e.g., “unbroken,” “unseen”). The prefix “in-” (which can also appear as “il-,” “im-,” or “ir-” depending on the following letter) often comes from Latin and is typically used with words of Latin origin (e.g., “inactive,” “impossible,” “illogical,” “irresponsible”). While there are no hard-and-fast rules without exceptions, recognizing the Latin roots of words like “excusable” helps in correctly applying the “in-” prefix.
This pattern is also evident when considering whether inconsiderate or unconsiderate is the correct form.
