strictly
UK: ˈstrɪktli | US: ˈstrɪktli
adv. in a strict manner; with precision or exactness
adv. without exception or deviation
The word "strictly" derives from the Latin strictus (past participle of stringere, meaning "to tighten or bind"). The root strict entered English via Old French estrict, retaining its core sense of rigidity or tight control. The suffix -ly (from Old English -līce) transforms the adjective into an adverb, emphasizing manner or degree. Together, the morphemes convey the idea of adhering tightly to rules or standards.
The teacher enforced the rules strictly.

The contract terms must be interpreted strictly.
The event is strictly for members only.
