Definition
A Latin term from Roman civil law meaning "sent across the sea." Trajectitius describes money, goods, or obligations that are transmitted or transported overseas — typically in the context of maritime lending. The term appears most commonly in the phrase *pecunia trajectitia*, denoting money lent for a sea voyage, where repayment was contingent on the safe arrival of the ship or cargo. Because the lender assumed the risk of loss at sea, such loans commanded higher interest rates than ordinary loans made on land. The term thus marks a specific legal category of obligation defined by its maritime, transoceanic character.

Why It Matters in Research
Trajectitius is a term of Roman civil law that entered English legal dictionaries primarily as a reference point for understanding maritime loan instruments. Researchers working in admiralty law, merchant law history, or the law of interest and usury will encounter it most often through its compound form, *pecunia trajectitia*, rather than as a standalone term. Historical sources that address bottomry bonds — loans secured against a ship or cargo, repayable only on safe arrival — are the primary English-language context in which trajectitius appears, even when the Latin term itself is not used.
The key research trap is treating trajectitius as an isolated curiosity rather than as the conceptual ancestor of the bottomry bond. The Roman law of *foenus nauticum* (maritime interest) and *pecunia trajectitia* directly informed how early English admiralty courts and civilian jurists understood risk-shifting in maritime lending. Researchers tracing the history of bottomry through English sources may need to work backward through civilian and Roman law materials to find substantive doctrine, since the Latin terminology drops away in later common law practice even as the underlying commercial structure persists.
Jurisdictional variation matters here primarily along the common law / civil law divide. Civil law jurisdictions and their historical sources — including ecclesiastical courts that enforced maritime contracts and treated *foenus nauticum* as an exception to usury prohibitions — will use trajectitius and its derivatives more freely than common law sources, which absorbed the same concepts under English commercial vocabulary.

Historical Dictionary Support
The three source dictionaries are in complete agreement and uniformly minimal: all three render trajectitius as "sent across the sea" and classify it as a term of Roman civil law. Burrill's alone adds the etymological root (*trajicere*, to send across) and the critical cross-reference to *pecunia trajectitia*, which is where the substantive legal content resides. Black's in both editions omits even that cross-reference, leaving the entry as little more than a translation gloss.
What all three sources miss is the doctrinal significance: trajectitius is not merely a descriptive adjective but a legal classifier that triggered a distinct regime of obligations under Roman law. Money classified as *pecunia trajectitia* was subject to special rules governing interest (*foenus nauticum*), risk allocation, and enforceability — rules that were exceptional precisely because ordinary usury limits did not apply when the lender bore the risk of maritime loss. Historical dictionaries that define the term without explaining *why* it existed as a legal category leave researchers without the context needed to use it productively.

Jurisdictional Note
Trajectitius and *pecunia trajectitia* are creatures of Roman civil law and appear in English legal sources primarily through admiralty and ecclesiastical court practice, which retained civilian learning longer than common law courts. The concept migrated into English commercial law through the bottomry bond but shed its Latin terminology in the process. Researchers working in Scottish, Continental European, or Latin American legal history — where civilian tradition remained dominant — will find the term and its derivatives in more active use across a longer historical period.
