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.

at·tacker n.

Synonyms: attack, assail, storm, assault, batter, beset
These verbs, drawn from military activity, mean in their figurative senses to act forcefully or aggressively toward someone or something. Attack applies especially to hostile verbal criticism: reviews that attacked the film for its senseless violence; attacked the ruling as detrimental to business interests.
Assail suggests repeated forceful attacks: Critics assailed the author's second novel.
Storm refers to a sudden sweeping attempt to overwhelm or win over: "After triumphantly storming the country, [the President] is obliged to storm Capitol Hill" (The Economist).
Assault and batter can suggest relentless attack or debilitating force: "We are all assaulted by so many messages battering us from the outside every hour of the day that our capacity for listening to our own inner voices is often drowned out" (Harvey Cox).
Beset suggests beleaguerment from all sides: "Rural and suburban areas have been beset by white-tailed deer gnawing shrubbery and crops, spreading disease" (Andrew C. Revkin).
