Ellipsis

An ellipsis represents omitted or trailing content; its character form and surrounding spaces must follow the publication’s language and style.

Definition

Unicode U+2026 is a single ellipsis character, while three full stops are three separate characters. Some editorial systems deliberately use spaced periods; therefore conversion is safe only when the project expects the single character.

BAD vs GOOD

BAD
Plain sequence

The result was... unexpected.

GOOD
Single character

The result was… unexpected.

Why it matters

A consistent ellipsis composes and spaces predictably, while mixed constructions can create uneven gaps or line breaks.

Rule strength

Strong character distinction; spacing is style-dependent. This is not an absolute linguistic law; locale, genre, content, and house style can change the correct decision.

Exceptions and editorial considerations

  • Some scholarly and editorial styles prescribe three spaced periods or special treatment at sentence boundaries.
  • Code and literal data may require three full stops.

How to fix it manually

  1. Confirm the house style.
  2. Replace only exact intended sequences.
  3. Review spaces before and after and proof sentence-ending cases.

Adobe InDesign guidance

Search for exact sequences and inspect surrounding punctuation; a blanket replacement can alter code or editorial notation.

How Avellio detects it

Avellio emits ELLIPSIS for three-period sequences and related ellipsis evidence.

Action safety

An exact guarded `...` sequence can enter Safe Clean; other contexts require review.

Language and locale differences

This principle has no separate Avellio locale override in the current registry; composition and house style can still affect judgment.
