Left first day outside, I have been in residence (5)
I believe the answer is:
lived
'been in residence' is the definition.
'lived' can be an answer for 'been' (living is a kind of being). I am not certain of the 'in residence' bit.
'left first day outside i have' is the wordplay.
'left' becomes 'l' (common abbreviation).
'first day' becomes 'd' (ist letter of 'day').
'outside' indicates putting letters inside (some letters go outside others).
'i have' becomes 'ive' (contraction of 'I have').
'l'+'d'='ld'
'ld' placed around 'ive' is 'LIVED'.
Can you help me to learn more?
(Other definitions for lived that I've seen before include "Existed or dwelt" , "Escaped destruction" .)
