Welcome lead singer to Rhode Island club. Unforgettable! (8)
I believe the answer is:
historic
'unforgettable' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'welcome lead singer to rhode island club' is the wordplay.
I cannot quite understand how this works, but
'welcome' could be 'hi' (both are greetings) and 'hi' is located in the answer.
'to' is within the answer.
'island' could be 'i' (geographical abbreviation) and 'i' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for historic that I've seen before include "Connecting with old times" , "sort of present" , "Pertaining to what is important in the past" , "Landmark; famous" , "Momentous, noteworthy" .)
