See a lot of paper as slightly yellowish (5)
I believe the answer is:
cream
'slightly yellowish' is the definition.
'cream' can be an answer for 'yellowish' (thesaurus). I'm not certain of the 'slightly' bit.
'see a lot of paper' is the wordplay.
'see' becomes 'C' (the word for the letter, according to Chambers).
'a lot of paper' becomes 'ream' (I've seen this in another clue).
'c'+'ream'='CREAM'
'as' is the link.
Can you help me to learn more?
(Other definitions for cream that I've seen before include "'There are more ways of killing a cat than choking it with ....." , "Best part of the milk" , "Very best; pale yellow" , "Elite; off-white" , "The best part -of the crop" .)
