{not available when compiled without the |+syntax| feature} Pattern to locate the end of a sentence. The following word will be checked to start with a capital letter. If not then it is highlighted with SpellCap |hl-SpellCap| (unless the word is also badly spelled). When this check is not wanted make this option empty. Only used when 'spell' is set. Be careful with special characters, see |option-backslash| about including spaces and backslashes. To set this option automatically depending on the language, see |set-spc-auto|.
