"Staggest" is not a correct spelling of a word in English. Perhaps what is meant is "stagger," which is pronounced /ˈstæɡər/ and means to walk or move unsteadily as if about to fall. It is spelled with two Gs, not three. Another possible word that could be intended is "staged," pronounced /steɪdʒd/ and means to organize and coordinate an event or production. It is spelled with a D at the end, not a double G. Correct spelling is essential for effective communication in English.
