Very iffy? (6)
I believe the answer is:
This might be a double definition.
'very' is the first definition.
'iffy?' is the second definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for mighty that I've seen before include "Arrogant people are often described as high and . . . . . ." , "Powerful - exalted" , "Having great strength" , "Extremely" , "Strong, powerful" .)
