Awkward waddle by royal time-waster (7)

I believe the answer is:

dawdler

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

'time-waster' is the definition.
I can't judge whether this definition defines the answer.

'awkward waddle by royal' is the wordplay.
'awkward' indicates anagramming the letters.
'by' is a charade indicator (letters next to each other).
'royal' becomes 'r' (abbreviation).
'waddle' is an anagram of 'dawdle'.
'dawdle'+'r'='DAWDLER'

Can you help me to learn more?

(Other definitions for dawdler that I've seen before include "Loiterer" , "Slow coach" .)

I've seen this clue in The Daily Express.
