Reply To: General question about grade 1 indicators
2.6.1 A letter or letters-sequence is considered to be "standing alone" if it is preceded and followed by a space, a hyphen or a dash. The dash may be of any length, i.e. the dash or the long dash.
This applies to all instances of letters separated by hyphens (except a, i, and o). To prevent "i-t-y" from being read as "i-that-you", the grade 1 word indicator is needed.
Using grade 1 symbol indicators would necessitate going in and out of grade 1 mode on multiple occasions, to be avoided. (5.9.1)
