I use the following preable in my document and I have a problem regardind hyphenation in new lines when I use both english and greek in my text. When I use only greek without the babel package then everything works fine and I have the proper hyphenation in greek text. But when I write in both languages if I have the babel package loaded then I don't get greek hyphenation. If I erase it I don't have english hyphenation. How can I fix that so to have hyphenation in both languages?

The problem occurs in this paragraph:

"Ένα πρότυπο (ή αντικείμενο) καθορίζεται από ένα διάνυσμα μετρήσεων (measurements) που ονομάζονται χαρακτηριστικά (features). Το διάνυσμα ονομάζεται διάνυσμα χαρακτηριστικών (feature vector)."

\documentclass[12pt]{article}

\usepackage[top=0.7in, bottom=1.2in, left=0.8in, right=0.8in]{geometry}

\setlength{\parindent}{0cm}

\usepackage{fontspec}

\usepackage{xltxtra}

\usepackage{xgreek}

\usepackage[english]{babel}

\setmainfont[
  Ligatures=TeX,
  Extension=.otf,
  UprightFont=*,
  BoldFont=*Bold,
  ItalicFont=*It,
  BoldItalicFont=*BoldIt,
  Mapping=tex-text,
]{GFSArtemisia}

\setsansfont[Mapping=tex-text]{GFSArtemisia.otf}

\usepackage[fleqn]{amsmath}

\usepackage{unicode-math}

\begin{document}

  • Remove xgreek (and also xltxtra, you just need fontspec, instead): it fights with babel; then \usepackage[greek,english]{babel} should do. Or use polyglossia.

  • @egreg I did what you said and I still get overful boxes because of the lack of hyphenation.

  • The paragraph in wquestion is this: "Ένα πρότυπο (ή αντικείμενο) καθορίζεται από ένα διάνυσμα μετρήσεων (measurements) που ονομάζονται χαρακτηριστικά (features). Το διάνυσμα ονομάζεται διάνυσμα χαρακτηριστικών (feature vector)."

You can use babel with English and Greek. But you must define what language you use.

You can do this with \selectlanguage and \foreignlanguage

Example:

\documentclass[12pt,greek,english,]{article}
\usepackage[top=0.7in, bottom=1.2in, left=0.8in, right=0.8in]{geometry}
\setlength{\parindent}{0cm}
\usepackage{fontspec}
\usepackage{xltxtra}
\usepackage[]{babel}

\setmainfont[
  Ligatures=TeX,
  Extension=.otf,
  UprightFont=*,
  BoldFont=*Bold,
  ItalicFont=*It,
  BoldItalicFont=*BoldIt,
  Mapping=tex-text,
]{GFSArtemisia}

\setsansfont[Mapping=tex-text]{GFSArtemisia.otf}
\usepackage[fleqn]{amsmath}
\usepackage{unicode-math}

\begin{document}

Wrong here:

Ένα πρότυπο (ή αντικείμενο) καθορίζεται από ένα διάνυσμα μετρήσεων (measurements) που
ονομάζονται χαρακτηριστικά (features). Το διάνυσμα ονομάζεται διάνυσμα 
χαρακτηριστικών (feature vector)

Correct here:

\selectlanguage{greek}
Ένα πρότυπο (ή αντικείμενο) καθορίζεται από ένα διάνυσμα μετρήσεων 
(\foreignlanguage{english}{measurements}) που ονομάζονται χαρακτηριστικά 
(\foreignlanguage{english}{features}). Το διάνυσμα ονομάζεται διάνυσμα 
χαρακτηριστικών (\foreignlanguage{english}{feature vector})


\end{document}

The result:

  • Isn't this very painstaking? I mean all I want is to write in 2 languages. Also I guess there are people who write in 3 or 4 languages some texts in their documents what are they doing? :P

  • How do you think TeX could recognize which language a text is? and inside this text to detect foreign words? For combinations of greek/latin writing (and e.g. arabic...) it may be possible (You could ask a new question for this). if \foreignlanguage{english}{...} is to long, you mey define a short version like newcommand{\grk}[1]{\foreignlanguage{greek}{#1}}.
