Looked into beginning to date after kiss on new year (1-5)
I believe the answer is:
x-rayed
'looked into' is the definition.
'beginning to date after kiss on new year' is the wordplay.
'beginning to' suggests taking the first letters.
'after' means one lot of letters go next to another.
'kiss' becomes 'x' (X can represent a kiss).
'on' indicates putting letters inside (as in clothing 'on' a person).
'new' indicates anagramming the letters.
The first letter of 'date' is 'd'.
'd' put after 'x' is 'xd'.
'year' with letters rearranged gives 'raye'.
'xd' enclosing 'raye' is 'X-RAYED'.
(Other definitions for x-rayed that I've seen before include "Photographed using radiation" , "Medically photographed" .)
