Pass Asian desert? Sounds like it (4)
I believe the answer is:
gobi
'it' is the definition.
The definition suggests a singular noun which matches the answer.
'pass asian desert? sounds' is the wordplay.
'pass' becomes 'go' (synonyms).
'asian desert? sounds' becomes 'bi' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'go'+'bi'='GOBI'
'like' is the link.
Can you help me to learn more?
(Other definitions for gobi that I've seen before include "Asian desert, Chinese name Shamo" , "Area of sand" , "very dry place" , "The . . . . Desert is a barren plateau of S Mongolia and N China" , "Arid region in central Asia, and 38 across" .)
