Welcome to my personal website!
My name is Roger Hartopp, and I am a writer, teacher, conversationalist, cartoonist and proof checker (and with my wife, translator of Polish texts). I am the author of a book called Typical Errors in English, and also manage a website of the same name which you can discover at .
Here are the latest bits of news concerning me and this site...

27 November 2022: Conversation rates for new students will be increased on January 1, 2023. The cost for a one-hour online lesson for all students joining on 1 January onwards will go up from 80 zlotys to 90 zlotys because of circumstances elsewhere and, unfortunately, the Polish government seemingly taxing sole traders to rates that will perhaps put many of us out of business. For all current students, I will keep the one hour rate for everyone at 75/80 zlotys until the end of the year, but as you know, events elsewhere are pushing domestic prices up. Even so, when compared to other native speakers on the Polish market, my rates are still lower than average!

24 November 2022: In CONVERSATIONS, ONE new topic added: logistics


19 October 2022: In CONVERSATIONS, ONE new topic added: are you a good student?

24 August 2022: Some general updates in all the conversation sections.

CURRICULUM VITAE. Who I am. My curriculum vitae. My resume. Whatever you like to call it, this is what I am about if you want to seriously consider me for some wonderful tasks.


CONTACT. If you want to write to me, speak to me, e-mail me, and so on...


CARTOONY UNIVERSE. Here are a few samples of artwork from my trusty pens. Some are shortly to be published in the book, one has been used for a company website, and others are just simply for my amusement. Do you want something similar for your company?


TYPICAL ERRORS IN ENGLISH. Are you a second language learner of English? If so, and if you are from Poland or Central Europe, or even from other European language countries, then this is the grammar book for you. Written and illustrated by myself, and published by TERTIUM, Typical Errors in English may be the book for you. So If you need someone who's good with their grammar...


STORIES AND POEMS. Are you a literary agent desperately looking for the next J.K.? Or Stig Larrson? You may wish to look further, but not before you check out some samples...

PROOFING. If you are a budding writer who has had their work translated into English but are unsure of the quality, I might be able to help check your texts.


PUBLICITY. Pictures and a report from my visit as a guest at the 19th annual book fair in Krakow, Poland. There are some press cuttings where I have helped to make the news, along with other materials such as publicity posters for my book.

Author, cartoonist, language instructor, English text proofing, and a definite sense of humour
