ITT: Troubadours Avoid Using Any Fifth Glyphs

[a-boy-playing-with-rubiks]

In my looking-orbs, word forms of ordinal digits is not similar to digit forms. So, "6th" isn't "sixth". My logic is that digit forms of ordinal digits is common among humans. But, my logic for not turning TABOO GLYPH into that third Arabic digit or schwa, list stops not, is that turning TABOO GLYPH into similar-looking glyphs isn't common, sans "no fifth glyph" posts.
