[Tex/LaTex] Replace the “AND” between authors’ names in citations and references with its equivalent in another language, e.g., Spanish

Question

I have been using the achicago package and the babel package for spanish language. When I employ the two, references with multiple authors are shown in the citations like (Mukange and Manamela) but it should (Mukange y Manamela) with a "Y", because the thesis is in Spanish. The same happens when the authors are listed in the bibliography.

Is there a way to change the "and" when authors are listed in a citation and in the bibliography for its equivalent in other languages?

Answer 1

Some BibTeX styles use \biband, or similar, instead of "and". You can have a look into the .bbl file to see if this is the case, and then renew that command to "y" in the main document.

If, instead, the BibTeX style writes a literal "and" in the .bbl, you are out of luck. In this case I would recommend you to create a customized BibTeX style using custom-bib. To do so, run the command:

$ tex makebst

and then answer a lot of questions about how do you want your bibliography. Give the answers that are consistent with the Chicago style you used to use. When asked about the "and", choose the \biband option. After all questions have been answered, you'll get a .bst file, which is the custom style you should use (\bibliographystyle).
