Two-Cell Word Sign Rules

$ ^dxh 6d )?8

Two-celled word signs can be used as parts of words.
If the letters of a word can be represented in the same space by outlining, then the word should be outlined rather than written with the two-celled sign.
Two-celled word signs that would not save any space as parts of words are not to be used in such words.
Exception: The two-celled sign for own should always be used in grade 3 braille to avoid confusion with the initial sign for re.
Two-celled word signs that do not save space by themselves must be used to represent the words for which they stand. They save space with their roles in sequencing.
The two-celled word signs with more than one meaning must not be used when their intended meaning is not obvious from context.
Two-celled word signs can be written without an intervening space with the word that follows, except:
- When the next word starts with be, con, or dis.
- When the next word is the contraction for to, into or by.
- When the resulting sequence would form an unintended word.
- When the following word begins with a punctuation or composition sign (italics or letter sign).
