I am writing my master thesis and I want to write down a sentence in Greek. Some years ago I used in another project for the same situation:


and when I had to write in Greek I was using:


In my current project instead I have this kind of settings:

\documentclass[11pt, english, ...]

What I just tried to do then is adding the polutonikogreek to the document class. Unfortunately it didn't work. By searching online then I found people saying to add the greek.polutoniko and so it became:

\documentclass[11pt, english, greek.polutoniko, ...]

And the package is loaded. Then, in order to write the text in Greek, I should use:


Unfortunately \textgreek{} is a call not recognized. So I moved forward and I saw some answers saying to use:


but it gives me back the error:

The fontspec package requires either XeTeX or LuaTeX.
You must change your typesetting engine to, e.g., "xelatex" or
"lualatex"instead of plain "latex" or "pdflatex".

So, at the end I wasn't able to write my sentence in Greek. Can you help me understanding how to do it please? Thanks in advance!

EDIT: This is my whole document class

\documentclass[11pt, english, singlespacing, headsepline, ]{MastersDoctoralThesis}
  • Have you used xelatex or lualatex then? – user31729 Aug 30 '16 at 11:21
  • @ChristianHupfer no, my bad. pdflatex is in my requirements. Sorry for forgetting to write it down – Enrico Ribelli Aug 30 '16 at 11:25
  • Is pdflatex really in your requirements, or an engine which outputs a .pdf file? – Bernard Aug 30 '16 at 11:28
  • See How do I write “amartia” in polytonic Greek, does it help? – Alenanno Aug 30 '16 at 11:30
  • @Bernard it really is in my requirements unfortunately – Enrico Ribelli Aug 30 '16 at 11:34

For a single sentence in Greek you don't need to load babel-greek. If you are using UTF-8 as the file encoding you can use the first way; otherwise use the transliteration below.




{\textgreekfont Πάτερ ἡμῶν ὁ ἐν τοῖς οὐρανοῖς}

{\textgreekfont\catcode`~=12 P'ater <hm~wn <o >en to~is o>urano~is}

  • This definitely solved my question! Thank you very very much! – Enrico Ribelli Aug 30 '16 at 16:48

Your custom class is already loading babel at line 155:

So if you load it again in your document, you get an Option Clash error. Now, a good rule of thumb is never to edit classes or packages, so to circumvent this, you can add \PassOptionsToPackage before the \documentclass is declared.


enter image description here


\PassOptionsToPackage{greek.polutoniko, main=english}{babel}
\documentclass[11pt, english, singlespacing, headsepline]{MastersDoctoralThesis}

Cosmos in Greek is \textgreek{Κόσμος}
  • Sometimes you don't have a choice but to edit the class or package, though. I have encountered a journal style file that redefines \p@ (among other cardinal sins...) – zwol Aug 30 '16 at 17:51
  • @zwol If the license of the class allows you to change it, you are free to do so. If a journal class redefines stuff, they have a pretty good reason. I wouldn't touch it. They won't care about your changes. – Johannes_B Sep 3 '16 at 12:16
  • @Johannes_B You maybe don't realize how disastrous redefining things in the guts of LaTeX can be... – zwol Sep 3 '16 at 19:06
  • @zwol I surely do. And i know, i can't simply change lines of The Lord of the Rings, and say it is the same. There are issues. – Johannes_B Sep 3 '16 at 19:55
  • @Johannes_B In the not-at-all-hypothetical situation with the journal style file that redefined \p@, what I did was fix it (with each change from the original clearly marked) and then put a README in with the sources to warn them that the document won't compile if they put back their version. And we'll see what happens. :-/ – zwol Sep 3 '16 at 20:06
