Mirum

Mirum is a Latin term that functions as the neuter singular form of the adjective mirus, meaning wonderful, marvelous, or strange. In classical Latin, mirum is used where a neuter adjective accompanies a neuter noun or appears in impersonal constructions such as mirum est, meaning “it is wonderful” or “it is remarkable.”

In usage, mirum often appears in set phrases and literary sentences to express surprise or admiration. The expression mirum est is common in Latin prose and poetry, where it serves as a concise evaluative clause. While mirus, mira, mirum are the standard gendered forms of the adjective, mirum specifically surfaces in contexts that require a neuter form or an impersonal, predicative function.

Etymologically, mirum derives from the Latin adjective mirus, connected to older Indo-European roots meaning admirable or remarkable. The form mirum demonstrates how Latin adjectives align with the gender and number of the noun they describe or with the impersonal predicate in fixed expressions.

Beyond classical Latin, mirum occasionally appears as a proper noun in modern contexts, where it is used in branding, product names, or fictional works. In such uses, the term is typically chosen to evoke ideas of wonder, curiosity, or distinction, though its meaning remains rooted in the original Latin sense.
