decrease logging » decrease lodging (Expand search), decrease flooding (Expand search), decrease owing (Expand search)
decrease good » decrease food (Expand search), decreases food (Expand search), decrease blood (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)

decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)
good object » word object (Expand search), good objective (Expand search), sound object (Expand search)

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease to decrease logging decreases ) OR ( decrease NOT decrease good object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease to decrease logging decreases ) OR ( decrease not decrease good object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease to decrease logging decreases ) OR ( decrease not decrease good object ))*.
