Question: What are the total occurence of words that paired with "nombre"?
SQL: SELECT SUM(T2.occurrences) FROM words AS T1 INNER JOIN biwords AS T2 ON T1.wid = T2.w1st OR T1.wid = T2.w2nd WHERE T2.w1st IN (( SELECT wid FROM words WHERE word = 'nombre' ) OR T2.w2nd IN ( SELECT wid FROM words WHERE word = 'nombre' ))
