Key Differences
"Expertise" is a commonly-used term that refers to the specialized skill or knowledge in a particular area. This term is often used to highlight proficiency and ability in professional and academic settings. "Expertize," on the other hand, is less frequently seen and is generally considered a British English variant of "expertise," although it may be used to refer to the act of giving expert advice or opinions.
Both "expertise" and "expertize" derive from the word "expert," but their usage and acceptability differ. While "expertise" is universally accepted in both American and British English, "expertize" is far more restricted in its use and often confined to British English. Unlike "expertise," which is strictly a noun, "expertize" can also function as a verb in certain contexts, meaning to act as an expert.
Grammatically, "expertise" is only a noun, whereas "expertize" can be both a noun and a verb. When "expertize" is used as a verb, it is usually in a specialized context. However, "expertise" enjoys wider usage and is the term you would most likely encounter in writing and conversation, whether you're in the U.S. or the U.K.
In summary, while "expertise" is a noun that refers to special skill or knowledge, "expertize" is largely its British English counterpart and has a secondary usage as a verb. "Expertise" is more universally accepted and understood, whereas "expertize" is less common and sometimes regionally confined.
