Less than tight clues back in Indy (5)
I believe the answer is:
tipsy
'less than tight' is the definition.
I can't judge whether this definition defines the answer.
'clues back in indy' is the wordplay.
'clues' becomes 'tips' (a tip is a hint or clue).
'back in' indicates one should take the final letters (the 'back' of the word).
The final letter of 'indy' is 'y'.
'tips'+'y'='TIPSY'
Can you help me to learn more?
(Other definitions for tipsy that I've seen before include "Rather drunk" , "A bit drunk" , "affected by drink" , "Merry, squiffy" , "Woozy" .)
