+# Prefix
+
+Prefix functions are symbols written directly in front of another term
+(without space). The term gets applied as an argument to the prefix
+function. Use [mixfix functions](mixfix.md) if the function has more
+than one argument.
+
+They are defined by the `‣`{.bruijn} suffix.
+
+Example:
+
+``` bruijn
+# defines a negation prefix function called '-'
+-‣ [(+0) - 0]
+
+# returns 0 - 10 = -10
+:test (-(+10)) ((-10))
+```
+
+You can use them as normal functions by writing the identifier
+literally:
+
+``` bruijn
+:test (-‣ (+10)) ((-10))
+```
