Definition
An archaic Law French term for bottomry — the practice of pledging a ship's hull (the "bottom") as security for a loan used to finance a maritime voyage. If the ship is lost at sea, the lender loses the loan; if the ship arrives safely, the borrower repays principal plus a premium. The term appears almost exclusively in historical legal sources and serves as a variant spelling of BOTTOMRY, which is the form used in modern legal writing.

Common Language
Modern common usage (Wiktionary): Listed only as an alternative form of "bottom-age," with no independent definition provided. The term has no meaningful life in contemporary general English.
Historical common usage (Webster's 1913): Not entered as a standalone term in Webster's 1913, which reflects that even by the nineteenth century the word had retreated entirely into legal and maritime specialist usage.
The gap here is not between legal and common meaning — both are effectively absent from ordinary usage. The significance of the term is purely documentary: a researcher encountering it in historical legal sources needs to know it is a synonym for BOTTOMRY, not a distinct concept.

Common Confusion
BOTTOMAGE vs. BOTTOMRY: These are not two different institutions. BOTTOMAGE is the Law French form; BOTTOMRY is the anglicized form that prevailed in English legal practice from the seventeenth century onward. Sources will use both spellings interchangeably in the early period. Researchers should not assume a substantive distinction between them.

Why It Matters in Research
This term functions almost entirely as a pointer. If you encounter BOTTOMAGE in a historical source — particularly in medieval or early modern maritime records, admiralty proceedings, or law French texts — it directs you to the doctrine of BOTTOMRY. The substance of the law is organized under that heading.
Burrill's entry is the most instructive of the three source dictionaries because it preserves a fragment of the original Law French: "Ceo est bottomage, quant argent est borrow surrhea" — roughly, "This is bottomage, when money is borrowed on [the ship]." This confirms that the term tracks directly to the pledge-of-hull concept and was used in French-language legal instruments before English terminology standardized around BOTTOMRY.
Researchers working in admiralty court records, early English commercial law compilations, or continental maritime codes may encounter BOTTOMAGE, BOTTOMRIE, or similar variant spellings depending on the source's date and national origin. Dutch, French, and Italian maritime law had parallel institutions under distinct names; do not assume that foreign-language variants are mere translations of the English term without checking the applicable legal tradition.
The term has no modern statutory or common law life. It will not appear in contemporary treatises or court opinions. Its research value is exclusively historical.

Historical Dictionary Support
All three source dictionaries — Black's (1st Ed.), Black's (2nd Ed.), and Burrill's — treat BOTTOMAGE identically: as a Law French synonym for BOTTOMRY, with no independent doctrinal content assigned to it. This uniformity is itself significant. It indicates that by the time these dictionaries were compiled, the term had already completed its migration into pure historical reference status.
Burrill's is the only entry that adds primary-source texture, reproducing the Law French formula. Black's entries in both editions simply cross-reference BOTTOMRY without elaboration. Researchers relying solely on Black's would be directed immediately away from this term; Burrill's provides the archival confirmation that the term was live usage in earlier practice, not merely a copyist's variant.
No historical dictionary examined here provides a substantive definition of BOTTOMAGE as distinct from BOTTOMRY, which is the correct treatment. Any source that implies a distinction should be viewed with skepticism.
