Understand I have to be unconscious (9)
I believe the answer is:
intuitive
'be unconscious' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'understand i have' is the wordplay.
'understand' becomes 'intuit' (I've seen this before).
'i have' becomes 'I've' (contraction of 'I have').
'intuit'+'ive'='INTUITIVE'
'to' is the link.
Can you help me to learn more?
(Other definitions for intuitive that I've seen before include "Using hunch" , "Sensed by something other than reason" , "with instinctive knowledge" , "Based on feelings" , "Innate" .)
