When used at the beginning of a statement, the adverb 尚（なお） ‘furthermore’ will often carry the meaning of ‘still’, ‘even’, or ‘yet’. This use is regularly seen after the previous statement ends in も, and will emphasize that ‘even after (A)’, or ‘even though (A) is a fact, (B) is still true’. Especially when the information expressed in the (B) part of the sentence is surprising or shocking in some way.
This structure will almost always appear without the kanji being used. Additionally, the (B) part of statements that include 尚（なお） will also frequently include も, in order to specify that the new information is ‘in addition to (A)’.
