The first argument (“num” in this example) is the name of a variable that will be used to choose which version of the sentence should be selected. The application interpreting the syntax will select the appropriate version of the sentence according to the value of this variable.
The second argument (“plural” in this example) states that the variable holds a numerical value. Alternatively, a “select” argument can be used, which specifies that the variable contains a text value corresponding to a keyword(plural or select) indicates whether the variable should be interpreted using pluralization rules or based on specific keywords (for non-numeric values). In general, if the second argument is plural, the variable from the first argument has a numeric value, if it is select, the variable will hold a text value.
Following the two arguments, there is a list of keywords: “zero”, “one”, “two”, “few”, “many”, “other” when using “plural”, or a custom set of keywords when using “select”.

Each keyword is followed by a sentence in curly brackets that corresponds to the plural form named by the keyword before it. These sentences can contain variables in curly brackets, but do not have to do so. You can use # as a number variable in “plural” (instead of writing the full variable name in curly brackets). If you do not want something (e.g. curly brackets) to be treated as a syntax element, you can escape it using an apostrophe.
