MP avoids ‘Harrumph’; turns it into cry of joy (6)

I believe the answer is:

hurrah

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

'mp avoids harrumph turns it into cry of joy' is the definition.
I can't judge whether this definition defines the answer.

'mp avoids harrumph turns' is the wordplay.
'avoids' is a deletion indicator.
'turns' is a reversal indicator.
'harrumph' with 'mp' removed is 'harruh'.
'harruh' backwards is 'HURRAH'.

Can you help me to learn more?

(Other definitions for hurrah that I've seen before include "One cheer?" , "Last ____, final act" , "Joyful exclamation" , "Bravo" , "A victory cheer" .)

I've seen this clue in The Hindu.
