how do you change the numbering of a question so that the subparts are numbered with greek symbols like alpha and beta instead of the usual roman numerals?

    It is hard to answer without some code we can play with. But take a look at the enumitem package, which provides the label key with which you can change the formatting. Though you'd have to define yourself a Greek counter formatter (e.g., here: https://tex.stackexchange.com/questions/4058/) – Skillmon Jul 04 '20 at 22:33
  • What have you tried, so far? – Davislor Jul 05 '20 at 02:03
  • \item[$\alpha$)] is easier. – egreg Jul 05 '20 at 08:11
  • Egreg, will that code automatically give me second part which is beta like the way english letter numbering comes e.g a), b), c), d) etc ? remember the first option is alpha and the second is beta. and will the (2) at the far right automatically appear? – Volvoman Jul 05 '20 at 09:24

The babel package defines localized Greek versions of \alph and \Alph. In fact, it provides four variants of them. One limitation is that all of them include the kerala, a prime symbol (ʹ) which is apparently correct for enumerating in Greek, but might not necessarily be what you want here.

If you want Greek letters without kerala, though, you could roll your own like the example in §8.1 of the enumitem mahual, or a more-readable version in expl3.

\documentclass{article}
\usepackage{iftex} % For \ifTUTeX

\pagestyle{empty} % Remove page numbers from this MWE


\ifTUTeX
  % Compiling with a Unicode engine.
  \usepackage[english]{babel}
  \usepackage{fontspec}
  \babelprovide[import,alph=lower.modern,Alph=upper.modern]{greek}


\babelfont{rm}
            [Ligatures={Common,TeX}, Language=Default]{CMU Serif}
\else
  % Compiling with an 8-bit engine.
  \usepackage[LGR,T1]{fontenc}
  \usepackage[greek,english]{babel}
\fi


\usepackage{enumitem}


\DeclareRobustCommand{\alphabeta}[1]{\foreignlanguage{greek}{\alph{#1}}}
\AddEnumerateCounter%
  {\alphabeta}%
  {\alphabeta}%
  {\foreignlanguage{greek}{\textomega}}


\DeclareRobustCommand{\AlphaBeta}[1]{\foreignlanguage{greek}{\Alph{#1}}}
\AddEnumerateCounter%
  {\AlphaBeta}%
  {\AlphaBeta}%
  {\foreignlanguage{greek}{\textMu}}


\begin{document}
\begin{enumerate}[label=\AlphaBeta]
  \item foo
  \item bar
  \item baz
  \begin{enumerate}[label=\alphabeta]
    \item meep
    \item freep
  \end{enumerate}
\end{enumerate}
\end{document}

Greek enumeration sample

You can italicize the labels like in your photo with something like label=\textit{\alphabeta*}. You can also give your label= a format such as \textgreek{\alph*} or \textgreek{\alph{enumi}}.

    +1 for the \alphabeta and \AlphaBeta numbering styles. – Mico Jul 05 '20 at 06:01
  • I would be grateful if you could add the way of how to get the greek labels without kerala since I didn't manage to do so. Thanks in advance! – Diaa Nov 23 '22 at 19:02
