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

'cheered' is the definition.
The answer and definition can be both to do with human feelings as well as being past participle verbs.
Maybe they are linked in a way I don't understand?

'ed dangled about' is the wordplay.
'about' is an anagram indicator.
'ed'+'dangled'='eddangled'
'eddangled' with letters rearranged gives 'GLADDENED'.

'and' acts as a link.

Can you help me to learn more?
