Jovial girl hated the dancing (5-7)

I believe the answer is:

light-hearted

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

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

'girl hated the dancing' is the wordplay.
'dancing' indicates an anagram.
'girl'+'hated'+'the'='girlhatedthe'
'girlhatedthe' anagrammed gives 'LIGHT-HEARTED'.

Can you help me to learn more?

(Other definitions for light-hearted that I've seen before include "Cheerful, carefree" , "Cheerful, unserious" , "Amusing, entertaining" , "Happy-go-lucky" , "Playful" .)

I've seen this clue in The Times.
