I have looked to your code.
First, `\stanza` don’t take argument. So delete the
Spoiler
{}
.
` \stanza Nun ghiastemmare, male te ne vene\&
\boaspeaks \stanza Facitav\`ella vuje chesta manovra.\&
\antspeaks \stanza Ma che nostromo si'? Da la paura & staje tremmanno da capa anz\'i a lu pede\dots & e che diavolo! & Paura d'affogare & nun l'avimmo: & chest'\`e lu rischio de chi va pe' mmare.\&
`
Second, I have hacked dramatist prevent the overloap. Add these line in your preamble.
`\makeatletter
\def\@character#1#2{%
\@namedef{#2}{{\namefont #1}\xspace}
\n@me@ppend@nddef{#2}{\@ppendname}{%
\if@drverse
{\speakstab\speaksfont{#1}\speaksdel\par\nobreak}
\else
\item[#1\speaksdel]
\fi}
}
\makeatother
`
But, indeed, I think you should learn how to do basic command. It’s not so hard… Do you read French ?
