Tree with lowered resistance, in consequence put down (7)
I believe the answer is:
entered
'put down' is the definition.
(I've seen this before)
'tree with lowered resistance in consequence' is the wordplay.
I cannot really understand how this works, but
an anagram of 'tree' is 'tere' which is within the answer.
The remaining letters 'end' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for entered that I've seen before include "Came in; recorded" , "Ten deer (anag) - went in" , "Put down" , "Enrolled or went in" , "moved in" .)
