Stenoscript or Stenoscript ABC is a shorthand system, originating in London 1607[1].
It is a phonetic system using longhand characters and punctuation. For this reason it has been criticised as not being a true shorthand system.
The system was intended to be a standardised form of abbreviation, requiring great mastery of recall. For example, ak stands for "acknowledge".
Although the system is generally slower to write in than more traditional shorthand styles such as Gregg or Pitman's shorthand, it has the distinct advantage of being decipherable to people not experienced in the system once applied in context.
For example
I ak . cl-n com-m
