Keyscript employs only the lower case letters of the alphabet.
Basically, the vowels in a word are omitted, leaving only the consonants.
The consonants are written phonetically, e.g. 'ph' is written as 'f'.
The vowels, and the least used English consonants in the alphabet are used as 'indicators'. Indicators show combinations of consonants which occur frequently in English. For example, in the word 'total', 'tl' is represented by the vowel 'e'. So 'total' becomes 'te'.
Common prefixes and suffixes are also represented by one letter, for example, 'self-' or '-self' is 's'.
There is a list of about 80 very common words that are written somewhat outside the rules of Keyscript so that they can be written with only one letter, for example, 'have' is 'v'.
Keyscript joins words together according to definite rules based on the natural flow of the English language, e.g. 'I am' is 'ym'.
Where the spelling of two words in Keyscript would be the same, and they could be mistaken in context, one of these is written slightly outside the rules, for example, 'amuse' is written as 'mus' to distinguish it from 'amaze', which is 'ms'.
Some common words are contracted further. For example, 'important' is 'mp'.
