Definition
An adverb of practice. To plead issuably means to plead in a manner that raises a material issue of fact for the jury to decide — that is, to file a plea that goes to the merits of the action rather than one that merely delays, objects to procedure, or otherwise avoids a direct engagement with the substance of the claim. When a defendant was put upon terms of pleading issuably, the court required that any plea entered tender a genuine triable issue rather than a dilatory or technical plea designed to postpone resolution.
Common Language
Modern common usage (Wiktionary): "In an issuable manner; by way of issue."
Historical common usage (Webster's 1913): "In an issuable manner; by way of issue; as, to plead issuably."
The common definitions here are not wrong, but they are empty without knowing what issuable means in its legal technical sense. In ordinary English, "issue" suggests a topic or problem. In the law of pleading, an issue is a specific point of fact or law that is formally joined between the parties and submitted for determination. Pleading issuably therefore means something precise: constructing a plea that actually joins such a point. The common definitions recycle the term without unpacking that technical content.
Common Confusion
Issuably is sometimes loosely read as meaning merely "in a way related to pleading an issue," which collapses it into the broader idea of issue-joining generally. The narrower and more accurate meaning is that the plea must be one going to the merits — an issuable plea — as distinguished from a dilatory plea, a plea in abatement, or any plea that addresses something other than the substantive right in controversy. A defendant put on terms of pleading issuably was being told, in effect: no more delay tactics; your next plea must be on the merits.
Why It Matters in Research
This term is a relic of common-law pleading practice and will almost exclusively appear in pre-code sources — English practice manuals, American treatises on pleading from the eighteenth and nineteenth centuries, and reported cases from that era. Researchers encountering issuably in historical case law or pleading texts should read it as a term of procedural discipline: courts used it when compelling defendants to stop using technical or dilatory pleas and to engage the action on its merits.
The operative reference in Burrill is Tidd's Practice, an English procedural treatise widely cited in American courts before code pleading replaced common-law forms. If you are tracing the usage of issuably, Tidd is a primary node in the citation chain.
After the Field Code (New York, 1848) and subsequent adoption of code pleading across American jurisdictions, the formal distinction between issuable and dilatory pleas largely dissolved into a unified system of answers and motions. Issuably effectively dropped out of American legal vocabulary. In English practice it persisted longer, but modern Civil Procedure Rules have similarly rendered it archaic. Researchers should not expect to find the term in twentieth-century or contemporary materials except in historical analysis or comparative law contexts.
The practical trap: a researcher reading an early American court order directing that the defendant "plead issuably" might misread it as simply requiring that the defendant file any plea at all. The order carries the more specific command that the plea tender a triable merits issue, and understanding that distinction can be critical to interpreting what procedural options remained available to the defendant at that stage of the litigation.
Historical Dictionary Support
Burrill's entry is spare but accurate: "In practice. In an issuable manner. The defendant is sometimes put upon terms of pleading issuably." The citation to Tidd's Practice, volume 1 at page 471, is the authoritative grounding. Burrill correctly flags the cross-reference to issuable plea, which is where the substantive content lives — issuably is purely the adverbial form and carries no independent legal weight beyond what issuable plea supplies.
No available historical dictionary entry elaborates further, and none need to. This is a term whose entire meaning derives from the parent concept. The Webster's 1913 definition, while technically accurate, provides no legal context. A researcher relying on Webster's alone would have no idea why the term appears in court records or what consequence it carried.
Jurisdictional Note
Issuably is a common-law pleading term with English origins. Its use in American jurisdictions tracks the period of common-law pleading practice, which ended at different times in different states as code pleading and then notice pleading were adopted. The term has no meaningful modern jurisdictional variation because it is no longer in active use in any American or English jurisdiction.
