JNO

Jno is a string that appears in historical documents and, less commonly today, as an acronym. In the context of onomastics and archival research, Jno is most often an abbreviation for the given name John or its variants Johannes, Ioannes, or Johan.

In English and Dutch records from the late medieval to early modern periods, scribes frequently used Jno. or Jno (with or without a period) as a compact form of John. This shorthand occurs in parish registers, wills, letters, and legal documents, where the full name would be repeated or understood from context. The usage reflects broader practices of name contraction common in manuscript culture, and modern transcriptions of these records often render Jno. as John.

In contemporary writing, Jno is rarely used as a personal-name abbreviation outside historical or genealogical transcription contexts. When encountered in all-caps form (JNO), it is typically an acronym or initialism whose meaning must be inferred from surrounding text, as there is no single standard definition across disciplines.

Overall, Jno primarily serves as a historic shorthand for John/Johannes in archival material, while in present-day text it appears mainly in transcription notes or as an acronym whose meaning depends on context.
