reviewwhether

Reviewwhether is a verb phrase used to describe the act of examining information or evidence in order to determine whether a proposition is true, false, or applicable. It is not typically listed as a single word in standard dictionaries; rather, it describes a pattern in which the verb review governs a subordinate clause introduced by whether.

Usage is most common in formal or technical writing, such as legal analysis, compliance reviews, policy evaluation, and research reporting. The construction signals a deliberate, evidence-based determination rather than a simple yes-or-no assertion. In many contexts writers prefer the two-word form "review whether" or rephrase to "assess whether" or "determine whether".

Grammatically, the "whether" clause functions as a content clause to be reviewed. Example: "The committee will review whether the contract has been executed according to the specified terms." The phrase can also appear with a noun complement: "a review of whether the policy was implemented."

Due to its formality and potential awkwardness in everyday prose, style guides often recommend alternatives depending on the emphasis: "review the evidence to determine if", "assess whether", or "evaluate whether". See also: yes/no questions, conditionals, and language about evaluation.
