This question already has an answer here:

I have a latex thesis template, written in english. I would like to use it in french but i didn't translate the defined layout like the word "chapter", " List of ...".

Have you any idea how to translate the layout.

    Do you use the babel package? Then pass the option french to it. Otherwise we definitely need to see your code (MWE). – TeXnician May 21 '17 at 11:04

    Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – Moriambar May 21 '17 at 11:05
  • Thank you for your response, when i use \usepackage[french]{babel}, i get this error : ! LaTeX Error: Option clash for package babel. – Fatma Belabed May 21 '17 at 14:37
  • In that case you need to show us an MWE and your template. But if it already loads babel it can be (it need not be at all) hard to get it to use French. Maybe the developer did not intend the template to be used with other languages. – moewe May 21 '17 at 15:26

    Put french in the documentclass options. – Johannes_B May 24 '17 at 12:36
