Definition
An obsolete term from old English law denoting the king's eldest son. The term appears exclusively in historical legal sources and has no operative meaning in modern law. It survives only as an antiquarian curiosity, preserved in legal dictionaries as a relic of medieval English royal nomenclature.
Common Language
Modern common usage (Wiktionary): Not attested as a recognized entry in modern general dictionaries.
Historical common usage (Webster's 1913): Not attested.
Editorial note: The term has no living presence in either common or legal English. Its closest surviving cultural trace is indirect: Black's itself notes the etymological thread running into the word "valet" and the figure of the knave in a standard deck of playing cards, where the knave (jack) follows the king and queen — a hierarchy that mirrors the royal succession logic embedded in the original term.
Common Confusion
"Vad Let" should not be confused with "valet" in its modern sense of a personal attendant or parking attendant, even though Black's explicitly draws the etymological connection. The legal term designated a specific status — heir apparent to the English throne — not a servant or attendant. The linguistic descent from royal heir to domestic servant reflects centuries of semantic drift, and importing the modern meaning back into historical legal texts would be a significant interpretive error.
Why It Matters in Research
This term falls into a narrow but important category for corpus researchers: terms that are formally defined in legal dictionaries but have no traceable footprint in case law, statutes, or legal practice. Its research value is almost entirely philological and historical rather than doctrinal.
Researchers working in medieval English royal law, succession law, or the history of titles of nobility may encounter this term in older treatises and Year Books. Its presence in a source can help date or contextualize a document, as the terminology belongs to a specific stratum of archaic English legal usage that had already become obsolete by the time Black's second edition was compiled.
The playing-card reference in Black's is not merely whimsical. It points toward a broader research thread: the way medieval social hierarchies left traces in popular culture and common objects. Researchers in legal history, semiotics of law, or the intersection of law and culture may find this note a useful citation anchor.
Be cautious of the Black's Supplemental citation itself. Supplemental material in early editions of Black's was sometimes drawn from Barrington's Observations on the Statutes (referenced here as "Bar. obs. St. 344"), a work that blends legal history with antiquarianism. Claims sourced through that channel should be treated as historically suggestive rather than doctrinally authoritative.
Historical Dictionary Support
Black's Law Dictionary (2nd Ed.), Supplemental, is the sole source in the Law Mind corpus for this term. The entry is brief and offers two pieces of information: the primary definition (king's eldest son in old English law) and the cultural footnote connecting the term to the knave in a card deck, citing Barrington's Observations on the Statutes at page 344.
No other major historical legal dictionary in wide circulation — including Bouvier's Law Dictionary or Tomlin's Law Dictionary — appears to have carried this term as a discrete entry, which underscores its extreme marginality even within the historical legal lexicon. The Black's Supplemental entry appears to have preserved it less for practical legal utility than for completeness and historical curiosity.
The Barrington citation is to Daines Barrington's Observations on the More Ancient Statutes, a real and well-regarded eighteenth-century work of English legal antiquarianism, which lends the etymological claim credibility even if the term itself was archaic well before Barrington wrote.
