Some compound words (like bus rapid transit, dog whistle, or identity theft) don’t appear on the drop-down list when you enter them into the search window. If a compound term doesn’t appear in the drop-down list, try entering the term into the search window and then hit the search button (instead of the “enter” key). Alternatively, begin searches for compound terms with a quotation mark.

Execute implies performing a task or putting something into effect in accordance with a plan or design: "To execute laws is a royal office; to execute orders is not to be a king" (Edmund Burke).
Accomplish connotes the successful completion of something, often of something that requires tenacity or talent: "Make one brave push and see what can be accomplished in a week" (Robert Louis Stevenson).
To achieve is to accomplish something, often something significant, especially despite difficulty: "Some are born great ... Some achieve greatness ... And some have greatness thrust upon them" (Shakespeare).
