In the short tex file below compiled with TeXShop 4.68, you can see that my \bigskip on line 8 is ignored (no vertical space between the title and the text) ; also the last-but-one line in the output is a blank line I didn't ask for in the source. Where does this come from ? How may I fix it ?
\documentclass[12pt]{book}
\usepackage[a4paper,margin=1cm,nohead,foot=0.5cm]{geometry}
\usepackage[utf8]{inputenc}
\pagestyle{plain}
\begin{document}
\bigskip
\noindent{\large\bf Kyrie} (p. 91)\newline
\bigskip
Kyrie, eleison. Christe, eleison. Kyrie, eleison. (3x3)\newline
\bigskip
{\large\bf Gloria} (p. 92)\newline
\bigskip
Gloria in excelsis Deo ; et in terra pax hominibus bonae voluntatis.\newline
Laudamus te.\newline
\end{document}
Output :


\bigskipisn't ignored, it causes the vertical space after the first line, as you show. – David Carlisle Oct 16 '21 at 09:07
