<nowiki><noinclude>{{subpages}}</noinclude></nowiki>

1. DELETE the 'nowiki' tags and their <> brackets in the line above, but keep the 'noinclude' tags and the 'subpages' template. ('Nowiki' renders everything between its tags as just raw text, so the template wouldn't work. But without them the top line would be blank when this editing window loads because of 'noinclude', which we need to keep to stop the template displaying menus in error elsewhere. It's a workaround.)

2. DELETE THESE NOTES after reading and replace them with just your definition. Put your definition on the blank second line above: maximum one sentence of 150 characters, ignoring formatting characters. Don't include the term defined in the definition itself, and start the text with a capital letter. 10-30 words are usually enough. Further details of how a definition should look like are given at https://en.citizendium.org/wiki/CZ:Definitions#Format_of_Definitions
