# accent above a greek letter

I want to make the greek letter omega with an accent above it.

I know that I make the letter in math mode:

$\omega$


and I know that I add a accent this way:

\'{e}


But when I combine the two:

\'{$\omega$}


I just get the accent before that omega, not above it.

• Is this a math mode application, or are you trying to write polytonic Greek letters -- in text mode, presumably?

• It wasn't in math mode. But I thought that I had to be in math mode to create the \omega. The \acute{} method worked for me. Mar 30, 2015 at 23:59
• There's a big difference, typographically speaking, between the polytonic (accented) "ώ" character and the output of $\acute{\omega}$.

• @Mico Do you know how we can type the polytonic epsilon in text mode in LaTeX/beamer? I'm trying to do this outside of math mode. Jan 14, 2020 at 0:49
• @Ernesto - I would think carefully before using a serif font, such as a Times Roman clone, for a beamer document. If at all possible, do use a sans-serif OpenType text font, such as Calibri or Noto Sans, which features a full set of polytonic Greek characters. Then, use either LuaLaTeX or XeLaTeX, which allow you to employ OpenType font families directly, to compile the document.

Use \acute{} in mathmode:

$\acute{\omega}$


Other accents in mathmode:

\documentclass{article}
\renewcommand{\arraystretch}{1.5}

\begin{document}

\section*{Accents in mathmode}
$\begin{array}{llll} \underline{\omega} & \verb|\underline{\omega}| & \overline{\omega} & \verb|\overline{\omega}| \\ \hat{\omega} & \verb|\hat{\omega}| & \check{\omega} & \verb|\check{\omega}| \\ \tilde{\omega} & \verb|\tilde{\omega}| & \acute{\omega} & \verb|\acute{\omega}| \\ \grave{\omega} & \verb|\grave{\omega}| & \dot{\omega} & \verb|\dot{\omega}| \\ \ddot{\omega} & \verb|\ddot{\omega}| & \breve{\omega} & \verb|\breve{\omega}| \\ \bar{\omega} & \verb|\bar{\omega}| & \vec{\omega} & \verb|\vec{\omega}| \\ \end{array}$
\end{document}
