What does mandatorily mean?
Mandatorily means that something must be done because an authority, rule, or formal requirement says so. It is an adverb: it modifies a verb, an adjective, or another part of speech to show that the relevant action is compulsory rather than optional. For example, a notice may state that protective equipment must be worn mandatorily, or that employees must attend training mandatorily. The word is especially associated with legal, institutional, workplace, safety, and administrative language. In less formal settings, forms such as “must,” “has to,” and “is required to” are usually clearer and less mechanical. Although mandatorily clearly conveys compulsion, using it repeatedly can sound repetitive, especially in a short passage. Its usefulness lies in making explicit, in formal wording, that an obligation applies and that compliance is not discretionary.
