Give lessons covering tips, advice, opinions, ideas, suggestions for a job in the house (9)
I believe the answer is:
taoiseach
'a job in the house' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'give lessons covering tips advice opinions ideas suggestions' is the wordplay.
'give lessons' becomes 'teach' (I can't explain this - if you can you should give a lot more credence to this answer).
'covering' is an insertion indicator.
'tips' suggests taking the first letters (I've seen 'tip of' mean this).
The initial letters of 'advice opinions ideas suggestions' is 'aois'.
'teach' placed around 'aois' is 'TAOISEACH'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for taoiseach that I've seen before include "PM in Dublin" , "Leader of the government" , "I 'ate chaos (anag) - Irish Republic's prime minister" , "Irish PM" , "Irish head of government" .)
