I'm using the para option to typeset table notes as a single justified text block, which often works, but not always. The attached code produces this:
There is a break between "b" and "c". It seems that threeparttable checks whether it can save a line by putting it all into one block, and if not it doesn't. But that can yield some ugly line-breaks, which make my document appear inconsistently formatted. How can I instruct it to always append all entries without breaking the line, so that the result looks like this:

Code:
\documentclass[12pt,a4paper]{article}
\usepackage[english]{babel}
\usepackage[para]{threeparttable}
\usepackage{blindtext}
\usepackage{booktabs}
\renewcommand\TPTminimum{\linewidth}
\begin{document}
\blindtext[1]
\begin{table}[!tbh]
\begin{threeparttable}
\begin{tabular}{cll}
\toprule some&table&content\\\midrule
1&2&3\\\bottomrule
\end{tabular}
\begin{tablenotes}
\item aaaaaa aaaaaaaaa aa a aaaaaa aaaaaaaaa a a a aa
\item bbb bbbb b bbbbbbbbb b bb bbbbbb b bbbb b bbbbbbbbb b bb bbbbbbbbb bbbb b bbbbbbbbb b bb bbbbbb b bbbb b bbbbbbbbb b bb bbbbbb
\item ccc ccc c c cccccc c c cccccc c c cccccc c c cccccc c c cccccc c c ccc c c cc
\end{tablenotes}%
\end{threeparttable}%
\end{table}
\end{document}
EDIT: I edited the code, removing a few "c"s from it, the original code did not fit the screenshot.
EDIT2: There's a related issue here: threeparttable notes layout, and the solution might help answering my question. I just can't seem to find out how.
\renewcommand\TPTminimum{\linewidth}. main features ofthreeparttableis that notes is below table and that they are not wide then table (as i understand it). – Zarko Mar 13 '18 at 16:50tablenotesenvironment likes adding line-breaks before\items. In my actual document tables are as wide as the text, thus the problem then remains the very same. Only, for the MWE I used a smaller table. – sheß Mar 14 '18 at 10:07
