horridly

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

'unkindly' is the definition.
Both the definition and answer are adverbs. Maybe they are linked in a way I don't understand?

'eccentric hid lorry' is the wordplay.
'eccentric' is an anagram indicator.
'hid'+'lorry'='hidlorry'
'hidlorry' is an anagram of 'HORRIDLY'.

Can you help me to learn more?
