Some children woken and got up by landlord (5)
I believe the answer is:
owner
'landlord' is the definition.
(I know that landlord can be written as owner)
'some children woken and got up' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'got up' says the letters should be written backwards.
'renwo' is hidden in the letters of 'children woken and'.
'renwo' reversed gives 'OWNER'.
'by' acts as a link.
(Other definitions for owner that I've seen before include "The one in lawful possession" , "possessive type" , "Keeper" , "Title-holder" , "One who has something" .)
