Basic being into each other (8)
I believe the answer is:
inchoate
'basic' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'into each other' is the wordplay.
'other' is an anagram indicator.
'into'+'each'='intoeach'
'intoeach' is an anagram of 'INCHOATE'.
'being' acts as a link.
Can you help me to learn more?
(Other definitions for inchoate that I've seen before include "Rudimentary, not fully formed" , "Imperfectly formed" , "just beginning" , "Unfinished" , "Only half-formed" .)
