Word Nuance & Usage

The plural of 'dictum' can be either the Latinate 'dicta' (preferred in formal and legal contexts) or the Anglicized 'dictums'. In law, it is frequently used as shorthand for 'obiter dictum', referring to a judge's passing remark that does not establish binding precedent.

Word Origin & Etymology

Borrowed in the late 16th century directly from Latin 'dictum', meaning 'something said' or 'a saying', the neuter past participle of 'dicere' ('to say' or 'to speak').
