 Some languages , such as French and Spanish , have academies that set language rules . Their publications typically address <unk> and grammar as opposed to matters of typography . Style guides are less relevant for such languages , as their academies set <unk> rules . For example , the <unk> française publishes the <unk> de l <unk> française for French speakers worldwide . The 1992 edition does not provide guidance on sentence spacing , but is single @-@ sentence @-@ spaced throughout — consistent with historical French spacing . The Spanish language is similar . The most important body within the Association of Spanish Language Academies , the Real <unk> <unk> , publishes the <unk> de la <unk> <unk> , which is viewed as <unk> for the Spanish language worldwide . The 2001 edition does not provide sentence spacing guidance , but is itself single sentence spaced . The German language manual <unk> des <unk> für Deutsche <unk> ( " <unk> of the Council for German <unk> " ) ( 2006 ) does not address sentence spacing . The manual itself uses one space after terminal punctuation . Additionally , the <unk> , the German language dictionary most commonly used in Germany , indicates that double sentence spacing is an error .
