In polyglossia, how can I change the English font in a Hebrew document

Question

I want to use polyglossia to write a Hebrew document with some English. The definition of the english font families only applies to English text included within Hebrew text (the word Corona), but not to standalone English text.

\documentclass[12pt]{article}
\usepackage{polyglossia}
\setdefaultlanguage{hebrew}
\setotherlanguage{english}

\newfontfamily\hebrewfont{David}
\newfontfamily\englishfont{Palatino Linotype}
\newfontfamily\englishfontsf{Lucida Sans}
\newfontfamily\englishfonttt{Lucida Sans Typewriter}
\parindent=0pt
\begin{document}
\begin{LTR}
\selectlanguage{english}
\textrm{The quick brown fox jumped over the lazy dog}\\
\textsf{The quick brown fox jumped over the lazy dog}\\
\texttt{The quick brown fox jumped over the lazy dog}\\
\end{LTR}
\begin{RTL}
לצערי ההרצאה בוטלה בגלל ה-
\textenglish{Corona}.
\end{RTL}
\end{document}

Answer 1

I think you just need to set it in a different environment. Here are several examples. Note that I changed the English font.

\documentclass[12pt]{article}

\usepackage{polyglossia}
    \setdefaultlanguage{hebrew}
    \setotherlanguage{english}
    \newfontfamily\hebrewfont[Script=Hebrew]{David}
    \newfontfamily{\englishfont}{Linux Libertine O}
    \newfontfamily{\englishfontrm}{Linux Libertine O}
    \newfontfamily{\englishfontsf}{Linux Biolinum O}
    \newfontfamily{\englishfonttt}{Libertinus Mono}
    
\parindent=0pt

\begin{document}

\begin{english}
    \begin{englishfontrm}
The quick brown fox jumped over the lazy dog.
    \end{englishfontrm}

    \begin{englishfontsf}
The quick brown fox jumped over the lazy dog.
    \end{englishfontsf}

    \begin{englishfonttt}
The quick brown fox jumped over the lazy dog.
    \end{englishfonttt} 
\end{english}


\begin{hebrew}
לצערי ההרצאה בוטלה בגלל ה-
\begin{english}\englishfontrm{Corona}\end{english}. 

לצערי ההרצאה בוטלה בגלל ה-
\begin{english}\englishfontsf{Corona}\end{english}.

לצערי ההרצאה בוטלה בגלל ה-
\begin{english}\englishfonttt{Corona}\end{english}.
\end{hebrew}

\end{document}
