anachronisms

I'm a little stuck... Click here to teach me more about this clue!

'colts given to normans say' is the definition.
I can't tell whether this defines the answer.

'chaotically cash in on arms' is the wordplay.
'chaotically' is an anagram indicator.
'cash'+'in'+'on'+'arms'='cashinonarms'
'cashinonarms' with letters rearranged gives 'ANACHRONISMS'.

Can you help me to learn more?

(Another definition for anachronisms that I've seen is " Things misplaced in time".)

I've seen this clue in The Telegraph.
