Archaism

Definition

Words and phrases that were standard in earlier English but have since fallen out of common use: 'hereinafter', 'aforesaid', 'witnesseth', 'whereas'. They persist in legal documents because drafters copy precedents, and changing them risks re-opening interpretive questions that past litigation has settled.

Examples
hereinafter, aforesaid, witnesseth, whereas
Context
Legal document drafting
Persistence reason
Drafters copy settled precedent language

Common questions

Why do lawyers keep using archaic terms that plain-language advocates criticize?+

Terms like 'aforesaid' or 'whereas' have often been interpreted by courts in prior litigation, so a drafter who swaps in modern wording risks introducing ambiguity that reopens questions the archaic phrase had already settled, favoring precedent over clarity.

How does archaism differ from other legal-language problems such as nominalization or passive voice?+

Archaism is specifically about obsolete vocabulary surviving by habit, whereas nominalization and passive voice are structural choices writers make in otherwise modern sentences; both contribute to reduced readability but archaism is the vocabulary-level symptom, not a sentence-structure one.
