Widows & Orphans
A widow or orphan is an isolated line of a paragraph separated from the lines it belongs with at the top or bottom of a column or page.
WIDOWORPHANDefinition
Widows and orphans weaken continuity because a small fragment is visually detached from its paragraph. Terminology varies between publishing traditions, so the practical concern is more important than the label: keep enough context together for the reader to follow the paragraph.
BAD vs GOOD
A paragraph continues… [page break] with only one line here.
A paragraph continues… [page break] Two complete lines remain on the following page.
Why it matters
An isolated line can look accidental, interrupt page rhythm, and make scanning harder. The defect is especially visible in books, reports, and multi-column layouts.
Rule strength
Strong composition convention. This is not an absolute linguistic law; locale, genre, content, and house style can change the correct decision.
Exceptions and editorial considerations
- Narrow measures, tables, captions, poetry, and heavily art-directed pages may require a documented exception.
- Fixing one page can create a worse break later in the story; inspect the complete reflow.
How to fix it manually
- Edit the copy without changing meaning.
- Adjust paragraph Keep Options where appropriate.
- Review tracking, hyphenation, spacing, or frame geometry within the publication’s tolerances.
- Recheck downstream pages after recomposition.
Adobe InDesign guidance
Use Paragraph Style Keep Options for repeatable control. Prefer paragraph-level composition settings over manual line breaks, then inspect the full threaded story after reflow.
How Avellio detects it
Avellio emits WIDOW and ORPHAN findings for isolated lines and extremely short paragraph endings in eligible composed text. The finding is geometric evidence, not proof that the page is wrong.
Publishing terminology and Avellio Issue IDs are related, but not identical. Avellio can label an extremely weak final body line as WIDOW even when it is not a classical top-of-column widow; ORPHAN is reserved for eligible single-line frame splits. Interpret the Issue ID together with its reason and page geometry.
Manual review only. Avellio does not automatically rewrite copy or alter Keep Options for this finding.
Language and locale differences
This principle has no separate Avellio locale override in the current registry; composition and house style can still affect judgment.
