gloriously

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

'in a wonderful way' is the definition.
I can't judge whether this definition defines the answer.

'ugly soil or mixture' is the wordplay.
'mixture' indicates an anagram.
'ugly'+'soil'+'or'='uglysoilor'
'uglysoilor' with letters rearranged gives 'GLORIOUSLY'.

Can you help me to learn more?
