Have you ever found yourself unsure whether to write irresistible or irresistable? You’re not alone. This is a common English spelling mistake because the endings -ible and -able often confuse writers. Many people naturally assume the word should end in -able, creating the incorrect spelling irresistable. However, only one version is accepted in standard English.
The correct spelling is irresistible. It is an adjective used to describe something or someone that is impossible to resist because it is extremely attractive, appealing, tempting, or compelling. You might describe a delicious dessert as irresistible, a person’s charm as irresistible, or an exciting offer as irresistible.
The misspelling irresistable usually happens because many English adjectives end with -able, such as comfortable, reasonable, and fashionable. However, irresistible follows a different spelling pattern and always ends with -ible.
