There I am, and я too, a single letter at the centre of the writing. U can be the reader. И, y and e put things together in pairs or strings, and other writers use single vowels and consonants – a, i, o, à, į, w, z, б, s, с – for basic meanings. Letters put together as acronyms and abbreviations offer to save time, but more frequently restrict common access, adopting new roles in the DNA of mystification. Some letters are at the heart of short messages, there to save space and foster ambiguity. Some letters are words, some stand in for words, and some don’t. OK?
