I would like to change the name "Σχήμα" to "Εικόνα" as you can see in the screenshot. Without babel it would be easy since I change the document element Figure to other word. How can I do it in babel. I tried \addto\captionsenglish{\renewcommand{\figurename}{Εικόνα.}. But it can not do it. My code is
\documentclass[12pt]{report}
\usepackage[english,greek]{babel}
\usepackage{graphicx}
\usepackage{tabularx}
\usepackage{multirow}
\begin{figure}[H]
\includegraphics[width=20cm]{PictureA.jpg}
\centering \selectlanguage{greek}
\caption{Αρχική κατάσταση. Μετωπιαία όψη.}
\end{figure}
\end{document}


\addto\captionsgreek{\renewcommand{\figurename}{Εικόνα.}}and not\captionsenglish. – moewe Aug 29 '21 at 09:21\listoffiguresis the entire command that prints the list of figures.\listfigurenameis the heading that you get from\listoffigures. See the list in https://tex.stackexchange.com/q/82993/35864. – moewe Aug 29 '21 at 10:19\AtBeginDocumentis not correct, because the default string is restored when the language is selected. – Javier Bezos Sep 06 '21 at 07:34
