# Lower-case roman numerals in enumerate with Spanish babel

I want to use lower-case roman numerals in a list, and I used:

%Redefine the first level
\renewcommand{\theenumi}{\Roman{enumi})}
\renewcommand{\labelenumi}{\theenumi}

%Redefine the second level
\renewcommand{\theenumii}{\roman{enumii})}
\renewcommand{\labelenumii}{\theenumii}


But I get upper-case roman numerals for both the first and the second level (I actually get smaller roman numerals for the second level).

Is there a way to use lower-case roman numerals?

Here is an example of the code I used:

\documentclass[letterpaper]{article}

\usepackage[utf8x]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[spanish]{babel}
\usepackage{parskip}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{mathtools}
\usepackage{amssymb}
\usepackage{fullpage}
\usepackage{graphicx}
\DeclareMathOperator{\lcm}{lcm}

\newtheorem{mydef}{Definición}
\newtheorem{theorem}{Teorema}
\newtheorem{lemma}{Lema}
\newtheorem{proposition}[theorem]{Proposición}
\newtheorem{corollary}[theorem]{Corolario}
\newtheorem{remark}{Nota}

your code works fine here (I get lowercase roman numerals for the second level). Could you post a minimal working example (MWE) that shows the context where your code fails? – domenico Dec 5 '13 at 22:39
Ok, I've posted the entire code just to make sure is not the packages or something like that. – PJOX Dec 5 '13 at 22:46
It seems to be a package issue. Comment out \usepackage[spanish]{babel} and you will see. – azetina Dec 5 '13 at 22:47
if you want to keep babel replace \usepackage[spanish]{babel} with \usepackage[spanish,es-lcroman]{babel}. the option es-lcroman will do the trick. – domenico Dec 5 '13 at 22:51
@dcmst I invite you to post your comment as a possible answer. – azetina Dec 5 '13 at 22:54

You can find more information about this issue in this blog (in Spanish) and in the babel-spanish manual at page 4 (again, in Spanish).
Lower case roman numerals can be restored via the es-lcroman option, which is documented at the same page of the babel-spanish manual.
The result with \usepackage[spanish,es-lcroman]{babel} in the preamble is the following:
