Let in again (7)
I believe the answer is:
readmit
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">let in again</span>' is the definition.<br/ ><span class="explanation-format__explanation">('admit' can be a synonym for 'let in' so perhaps 'readmit' is OK for 'let in again')</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for readmit that I've seen before include "Welcome back" , "Again accept" , "Dear Tim (anag.)" , "Let back in" , "Let in a second time" .)
