la literatura » la litterature, a literature
studies deep » studies dewey, studies der, studies does
studied deep » studying deep, study deep, buried deep
tests scale » tests stable, sets scale, tests safe

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "tests scale ((studies deep) OR (studied deep)) filosofica la literatura*".
