On the other hand, it was the English who used to have some extra space between sentences compared to the space between words. This is still the default in LaTeX, but I believe everyone turns it off by using the \frenchspacing command in the preamble.

Also German has its own verbs for "for the insertion of inappropriate spaces before a punctuation mark." and "for the insertion of inappropriate spaces after a punctuation mark."[1] which are often used in a derogatory manner in connection with people who do it wrongly.
