Very close, though filling wide area (4)
I believe the answer is:
dear
'very close' is the definition.
'dear' can be an answer for 'close' (similar in meaning). I'm unsure of the 'very' bit.
'filling wide area' is the wordplay.
'DEAR' is hidden in amongst the letters.
But, I am unsure how the hidden word is indicated.
'though' acts as a link.
Can you help me to learn more?
(Other definitions for dear that I've seen before include "Pricey" , "Expensive or loved" , "It's not cheap" , "Precious" , "Honey - costly" .)
