Re: There is no such verb as "to pen"
Technically, the verb 'type' comes from exactly the same standard. In Middle English the word 'type' meant a symbol, most often a carved one, thus pressing carved (or moulded) symbols against paper to make words became typing. Though there was an intermediate stage where people set types into frames in order to print pages at a time which was known as typesetting.
Type meaning category came later and also referred to a symbol representing that category.
