# Tilde over greek letter in text

how can I get a tilde over the greek letter nu in text. I am using:

\usepackage{textgreek}


I tried

\~\textnu


but that gives the tilde in front of the letter and not above it.

Thanks!

• Can you add a minimal working example (MWE) to your question? I just tried \documentclass{article}\usepackage{textgreek}\begin{document}\~\textnu\end{document}, and that does indeed produce a tilde above the letter, as intended.

• @chsk I don't get it. And, knowing how \~ is defined, it cannot work. Mar 18, 2021 at 22:16
• @egreg That's really strange. I just tried again, and even though it perhaps cannot work, it definitely does. What gives?

• For later reference, this is because I was using xetex (where using textgreek is not a good idea to begin with). Thanks to David Carlisle and Ulrike Fischer!

You can use the LGR encoding for the job, using the fact that the tilde accent exists in it.

\documentclass{article}
\usepackage{textgreek}

\newcommand{\tildenu}{{\fontencoding{LGR}\selectfont\accperispomeni\textnu}}

\begin{document}

\tildenu

\end{document}


If you want the tilde like in the Latin font, you have to go the hard way.

\documentclass{article}
\usepackage{textgreek}

\newcommand{\tildenu}{%
\leavevmode\vbox{\offinterlineskip
\ialign{\hfil##\hfil\cr\~{}\cr\noalign{\kern-1ex}\textnu\cr}%
}%
}

\begin{document}

\tildenu

\end{document}


• Hi, just a curiosity. Why in my screenshot have the tilde not true bold than your (your first screenshot) :-)? Is it your MacOS? :-) Mar 18, 2021 at 22:29
• @Sebastiano They're the same, only at different resolutions. Mar 18, 2021 at 22:44
• Ah, thank you very much for your explanation. Mar 18, 2021 at 22:45

Probabily you can use this MWE:

\documentclass[a4paper,12pt]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[greek]{babel}
\begin{document}
\textgreek{o\~nios}
\end{document}


You can use

$\tilde{\nu}$


or

$\widetilde{\nu}$


With XeLaTeX you could use

\textnu\char"0303


or (provided that you load a font that supports Greek)

\char"03BD\char"0303

• Or you could directly use ν̃ which is more readable. Mar 19, 2021 at 8:45
• Indeed.Then you need to have the file Unicode encoded of course. Mar 19, 2021 at 9:00
