Marcus visited Estonia for the first time in spring 2003 and in the autumn of the same year started to English language editing a text by a highly respected Estonian social scientist.

The process of language editing the English text of a ‘speaker of another language’ proved to be a steep learning curve – this initial contract took almost 5 months to complete!

In 2004, Svennik Høyer of the Institute of Media and Communications at the University of Oslo asked Marcus to language edit the chapters of a book he was co-editing with Horst Pöttker – The Diffusion of the News Paradigm 1850-2000 – which Nordicom published in 2005. The rest, as they say, is history.

On 7th August 2006, Marcus established OÜ Derettens to provide English Language Editing Services to scholars anywhere in the world.



1st Language Editor British


2nd Language Editor British

Derettens offers 11 English-language editing services in 2 packages:


€5.50 per LEU

€11 per LEU

To calculate the cost of the language editing of your text, you will need to apply the formula:
€Cost = Total ciws ÷ 1700 x €5.50 OR €Cost = Total ciws ÷ 1700 x €11.00

C I W S = characters including white spaces (available alongside word counts in word processors)
LEU is a Language Editing Unit = 1700 CIWS
