For a word shown in syllables, follow the basic contraction rules of
Sections 10.1 to 10.11. In particular, do not use an alphabetic
wordsign for a syllable of a word shown in syllables.
Except as provided for in Rule 10.12.1, use contractions in
abbreviations and acronyms, following the provisions of Section 5.7.1
and 5.7.2, Grade 1 Mode, as well as those of Section 10.1 to 10.11.
Use contractions in computer material, such as email addresses, web
sites, URLs, and filenames when it is embedded in regular text. Use
uncontracted braille for computer material, such as computer
program code which is displayed on separate lines, as well as any
nearby excerpts from the program.
For words in dialect, follow the contraction rules, 10.1 to 10.11.
For fragments of words, follow print and follow the contraction rules,
10.1 to 10.11.
Several contraction rules are based on the pronunciation and/or
syllabification of the word. The Preference rule states that a
contraction is not to be used when it would "hinder the recognition of
the word". Sections 10.10.8 and 10.10.9 (the Preference rule) refer
to the pronunciation of a word.
When the word is unfamiliar and when the pronunciation or
syllabification is unknown and difficult to ascertain, then it is permissible for contraction use to be based on the best judgment of
the transcriber and/or proofreader. When translation software is
being used, its contraction usage may be followed.
The guidelines relating to unknown pronunciation or syllabification
apply in particular to proper names, abbreviations, acronyms,
contrived words (as in science fiction) and anglicised foreign words.
In all cases, consistency within a transcription is required.
Note: It is preferable that transcribers do not divide words at the end
of a braille line. Be aware that the braille authorities of some
countries have specific guidelines on word division and such
guidelines if available should be followed. However, when words do
need to be divided at the end of a line, observe the following
