#### Usage notes

Sometimes the noun equivalent to denote a comparable option is assailed for falsely implying absence of difference (false equivalence); when this problem arises, the noun counterpart, or a collocation such as rough equivalent or near equivalent, is sometimes a less misleading choice. In some contexts, the nouns analog or homolog are apt.
