Energised with self-confidence, takes rather too much linen (5,5)
I believe the answer is:
white goods
'linen' is the definition.
(thesaurus)
'energised with self-confidence takes rather too much' is the wordplay.
I cannot really see how this works, but
an anagram of 'with' is 'whit' which is within the answer.
'self' could be 'ego' (synonyms) and 'ego' is found in the answer.
'too much' could be 'od' (abbreviation for overdose) and 'od' is present in the answer.
A single letter 's' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for white goods that I've seen before include "Large appliances" , "Home appliances" , "Kitchen equipment" .)
