Paul & Co's irregular verbs? (7)

Ross

I believe the answer is:

copulas

'verbs?' is the definition.
(type of verb eg 'to be')

'paul co's irregular' is the wordplay.
'irregular' indicates an anagram.
'paul'+'cos'='paulcos'
'paulcos' with letters rearranged gives 'COPULAS'.

I've seen this clue in The Guardian.
