Definition
In Scots law, the period marking the termination of a tack (lease). ISH designates the end date or expiry point of a leasehold arrangement — the moment at which the tenant's right of possession under the tack comes to a close. It is the functional equivalent of the lease's expiration date in modern property law terminology.
Where a tack fails to specify the ish, the lease defaults to one year only, unless the instrument discloses an intent to run longer, in which case courts construe it to the minimum period the language can bear. A tack expressed to run in perpetuity presents a particular interpretive problem: the ish being indefinite, such a tack does not enjoy the protections conferred by statutes conditioning relief on a fixed termination date.

Common Language
Wiktionary: ISH is a pronunciation spelling of "is," or more commonly in contemporary informal usage, a suffix or standalone word indicating approximation or hedging (e.g., "we'll meet at noon-ish").
Webster's 1913: Not independently defined as a standalone entry; appears only as a suffix of Anglo-Saxon origin forming adjectives.
The gap here is total. The legal term ISH has no relationship whatsoever to either the informal modern usage or the adjectival suffix. A researcher encountering ISH in a Scots law document should treat it as a term of art describing lease termination, not as a textual artifact or approximation marker.

Why It Matters in Research
ISH is an almost exclusively Scots law term, encountered most often in historical Scottish property records, lease instruments, and litigation involving tacks. Researchers working in the Law Mind corpus should be alert to the following:
**Paleographic trap.** In early manuscript sources, ISH appears in archaic orthography — Burrill's cites the form "ische" and records the phrase "at the ische of ye quhilk terme" from a 16th-century criminal trial record. Researchers transcribing or reading original Scots documents may encounter variant spellings that are not immediately recognizable as the same term.
**Tack law dependency.** ISH is unintelligible without understanding the tack — Scots law's distinctive lease form that diverges meaningfully from English landlord-tenant concepts. The ish is not merely an end date; it carries specific legal consequences for renewal, holdover, and statutory protection that differ from how English courts treated lease expiry. Corpus connections run directly through TACK, TACSMAN, and the broader body of Scots heritable property law.
**Statutory interaction.** Bouvier's flags that a tack in perpetuity — with no defined ish — is excluded from statutory benefit. Researchers tracing specific Scottish leasehold disputes will need to identify which statutes are at issue, as the consequences of an indefinite ish varied across the statutory landscape of different periods.
**English reception.** Because Scots law operated as a distinct system even after the Acts of Union, ISH does not appear in English common law sources. Researchers using English-origin dictionaries or treatises will find no entry. The term's presence in Black's and Bouvier's reflects the encyclopedic tradition of capturing Scots and civil law terms for American practitioners handling cross-border or comparative matters, not evidence of adoption into Anglo-American common law.

Historical Dictionary Support
The four source dictionaries agree on essentials: ISH means the termination period of a Scots tack, and all four point to the same authority — 1 Bligh 522 — suggesting that a single House of Lords appeal (heard on appeal from Scotland, as Bligh's Reports covered) was the dominant precedent at the time of compilation.
Burrill's is the most linguistically detailed, tracing the term to Old Scots "ische" and quoting a 16th-century primary source directly. This makes Burrill's the most useful starting point for researchers needing to trace the term into manuscript-era Scots practice.
Bouvier's adds the most substantive legal content, explaining the default-to-one-year rule and the perpetuity problem — information absent from the Black's entries, which are essentially stripped definitions. Researchers relying solely on Black's for understanding ISH will miss the operative rules governing what happens when the ish is unspecified or indefinite.
The second edition of Black's contains an apparent printing error immediately following the ISH definition (the fragment "Lat. The cogIs cui cognoscitur, the cog-"), which is a typographical artifact from adjacent entries and should be disregarded entirely.
None of the historical dictionaries address what happens after ish — holdover, tacit relocation, or renewal — and researchers will need to consult Scots institutional writers (Bell, Erskine, Stair) for the full picture.

Jurisdictional Note
ISH is specific to Scots law and has no equivalent usage in English common law, Irish law, or American law. It may surface in colonial-era records in jurisdictions with Scottish settler populations, but only in documents explicitly governed by or referencing Scots legal practice. Modern Scots property law has substantially displaced tack terminology, though the concept persists in historical scholarship and heritage property contexts.
