Definition
A debt that bears no interest. The term originates in Roman civil law and describes an obligation to repay a principal sum without any accompanying obligation to pay interest — the money is "barren" in the sense that it produces no yield for the creditor. The concept stood in contrast to the ordinary expectation in commercial lending that money lent generates a return.
Common Language
Modern common usage (Wiktionary): "Barren" means producing little or no vegetation; by extension, unproductive, empty, or devoid of something.
Historical common usage (Webster's 1913): "Barren" — not producing offspring; unfruitful; sterile; hence, producing little or nothing; unprofitable.
The metaphor is direct and intentional: money that generates no interest is treated as a sterile or unproductive thing, incapable of yielding fruit. The common agricultural and biological sense of barrenness mapped cleanly onto the economic concept of non-yield-bearing debt, making this one of the more transparent metaphorical borrowings in legal terminology. A modern reader will grasp the image immediately, but may not recognize it as a formal legal classification with distinct doctrinal consequences.
Why It Matters in Research
This term appears almost exclusively in civil law contexts and in historical treatises addressing Roman-derived legal concepts. Researchers should be aware of several navigational considerations:
First, the term's practical significance in historical sources is tied to the ecclesiastical prohibition on usury. In periods and jurisdictions where interest-bearing loans were disfavored or prohibited, the distinction between a barren debt and an interest-bearing one had real legal and moral weight. A corpus search that encounters "barren money" in pre-modern English or Continental sources should be read against that backdrop.
Second, the term has no meaningful modern equivalent in U.S. positive law. Statutes and modern cases address zero-interest obligations without reference to this phrase. If the term appears in a modern document, it is almost certainly either a historical quotation, a translation artifact from a civil law source, or an archaic formulation in an older instrument being interpreted.
Third, researchers working on the history of interest, usury law, or the law of obligations in civil law systems (Louisiana, Quebec, mixed jurisdictions) may encounter this term more frequently than those working in common law commercial contexts. Its presence in a source is itself a signal about the intellectual tradition the author is drawing from.
Finally, do not conflate the term's narrow technical sense with broader discussions of non-interest-bearing instruments in modern finance law. Modern zero-coupon bonds, for example, are not "barren money" in any legally operative sense — the terminology does not travel.
Historical Dictionary Support
The historical dictionaries consulted are in complete agreement: Black's (both editions) and Bouvier's each define barren money identically as "a debt which bears no interest," attributing the concept to the civil law. The convergence across these sources reflects the term's settled, if narrow, doctrinal status.
Rapalje & Lawrence's entry is corrupted in the available text — the entry appears to have been typographically merged with adjacent entries (including material on barrenness as a ground for divorce and barratry), making their definition of the standalone term unreliable from the surviving text. However, the phrase "non-interest-bearing debt" is visible in the fragment, consistent with the other sources.
None of the historical dictionaries provide elaboration on what legal consequences attached to the classification, how courts distinguished barren from interest-bearing debts in practice, or how the doctrine interacted with usury rules. Researchers seeking that depth will need to move beyond dictionary sources to civil law treatises — Pothier's work on obligations is the natural starting point — or to historical scholarship on usury doctrine.
