"nosql" tends to mean more than simply not SQL. Often not any sort of relational structure and related querying methods, for instance, so "not nosql" is not the same set of things as "SQL".
And yet, you know that isn't the point and are just trying to have the last word.
SQL is not the only structured query language and SQL-queried databases are not the only relational databases. It just happens that the subset of database services that are not nosql and commonly “compete” with sqlite as a relational database mostly happen to use some variant for SQL.
