Auto spacing in math mode

Question

I have a long line of math expression, which is as follows:

$verylongword verylongword verylongword verylongword verylongword verylongword verylongword verylongword verylongword verylongword verylongword verylongword$

The problem is that the expressions denoted "verylongword" cannot be hyphenated to "very-long-word".

This results that in math mode the i can split text putting additional $ and \ (new lines). This means that some of the line ends are left as empty spaces, and text is not aligned properly, i.e. spacing between math is fixed and text is seen as $verylongword verylongword verylongword $(10 empty spaces).

Is there a way how to align such line in a nice automatic way, so as words within math expression would be automatically aligned adding extra spaces between math text?

Answer 1

The default in inline math mode is to stretch white space and justify lines to the specified width, if that is not happening in your real example you will need to show your real example.

\documentclass{article}

\begin{document}

$\mathit{verylongword}+ \mathit{verylongword}+ \mathit{verylongword}+ \mathit{verylongword}+ \mathit{verylongword}+ \mathit{verylongword}+ \mathit{verylongword}+ \mathit{verylongword}+ \mathit{verylongword}+ \mathit{verylongword}+ \mathit{verylongword}+ \mathit{verylongword}$

\end{document}

Note I used \mathit here as you should never set multi-letter words in the default math italic font.

Depending on the text you may want to let white space stretch more than usual, eg \sloppy on the example in comments.

\documentclass{article}
 \begin{document}

\noindent X\dotfill X

{\sloppy
  $\mathit{verylongword}+ \mathit{verylongword12}+
  \mathit{verylongword12}+ \mathit{verylongword12}+
  \mathit{verylongword12}+ \mathit{verylongword12}+
  \mathit{verylongword12}+ \mathit{verylongword}+
  \mathit{verylongword}+ \mathit{verylongword}+ \mathit{verylongword}+
  \mathit{verylongword}$

}
