[Tex/LaTex] How to prevent the orphan word of paragraphs

spacing

Currently, I have a paragraph in my article shown as following picture: the orphan word MAS. at the end of the paragraph takes a single line.

But somehow, there was one typeset which successfully removed the orphan word, and made the paragraph more compact, as the following picture shows: the word Thus, was successfully aligned itself with location. sentence, which results in a compact paragraph.

Unfortunately, I don't know how to control latex to reproduce this again. Could any one show me some useful skills to remove the orphan words like this?

If you put \looseness=-1 immediately before the paragraph TeX will try to make it one line shorter

[Tex/LaTex] the proper use of \@ (i.e., backslash-at)

i find the cited answer rather confusing, if not out-and-out backwards. \@ before punctuation says that the period does fall at the end of a sentence. to quote from the latex manual (p.170):

\@ Causes an "end-of-sentence" space after punctuation when typed before the punctuation character. Needed only if the character preceding the punctuation character is not a lowercase letter or a number.

so your farcical sentence is input as

Languages like JS, HTML, etc.\ were not used by King Henry III\@.

only one \@, and that after a capital I.

Update:
I have been reminded, rather ignominiously, that \@ is not defined in classic TeX. If used, the result is "! Undefined control sequence." (The corresponding command for TeX to render an end-of-sentence space following a period following an uppercase letter is \null.) \@ is LaTeX only.

[Tex/LaTex] \@ vs. \␣ after abbreviation. (Read backslash-at vs. backslash-space)

If you are putting them explicitly in the document, then it doesn't really matter. If you are making a macro it's better to use \@ form.

\newcommand\zzz{i.e.\@}
\newcommand\yyy{i.e.\ }
\newcomamnd\xxx{i.e.}

with \zzz you can use \zzz\ jjj or \zzz{} jjj and you get the correct spacing. With \yyy the spacing is forced (so it is not so good if you don't want any space at all as in \yyy, bbbbb ) and in \xxx you need to know the command ends with a non-sentence . so follow it with \ or \@ not {}.
