Wiped out text, start to finish, describing elected Conservative (7)
I believe the answer is:
extinct
'wiped out' is the definition.
(similar in meaning)
'text start to finish describing elected conservative' is the wordplay.
'start' indicates taking the first letters.
'to finish' means one lot of letters go next to another (some letters go after or 'finish' others).
'describing' becomes 'ext' (I can't justify this - if you can you should give a lot more credence to this answer).
'elected' becomes 'in' (in government).
'conservative' becomes 'C' (UK political abbreviation).
The initial letter of 'text' is 't'.
'ext'+'in'+'c'='extinc'
't' after 'extinc' is 'EXTINCT'.
Can you help me to learn more?
(Other definitions for extinct that I've seen before include "Put out" , "Permanently inactive" , "never to be seen again" , "finished" , "Ended" .)
