Usage notes emphasize that, in many kinds of writing, use is a simpler, more direct choice. Utilize tends to convey deliberate, practical application or optimization, and can impart a formal or technical tone. Critics argue it can be unnecessary or pretentious outside specialized writing. When choosing between use and utilize, consider audience and purpose. Common collocations include utilize resources, utilize data, utilize technology, and utilize a method or approach.
