Gives up F-word with no limits on curses? (9)

'gives' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their -s form.
Perhaps they are linked in a way I don't understand?

'up f-word with no limits on curses?' is the wordplay.
'up' is an anagram indicator (letters get chucked up).
'with no limits' says to take the centre (the sides or limits of the word are removed).
'on' is a charade indicator (letters next to each other).
'curses?' becomes 'swears' ('swear' can be a synonym of 'curse').
The central letters of 'word' are 'or'.
'f' put after 'or' is 'orf'.
'orf' anagrammed gives 'for'.
'for'+'swears'='FORSWEARS'
