I understand 'not so much A as B' = 'not A but rather B'
Q1: Would it be correct to understand 'They are not so much lovers as friends' =
'They are more like friends than lovers'
Q2: This question concerns over the position of the phrase 'so much'
Do the three sentences have the equal meaning?
'I don't feel angry; I am more sad.'
'I don't feel angry so much as sad.'
'I don't feel so much angry as sad.'
If the three sentences have the same meaning, then would it be right to accept that the position of 'so much' may vary, but the word 'as' always precedes the more important option, i.e. B from 'not A but rather B' ?'
