swash » slash, swath, smash
spat » spot, spam, spa
spate » spote, spame, spae, spater, spaten, space
span » spin
sweat » sweet, swept
-plate" » -plates"

Try widening your search to All Fields.

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: "(swash OR (((spat OR span) OR sweat) OR spate))(-plate" or -place").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(swash or (((spat OR span) or sweat) or spate))(-plate\" or -place\")".
• Removing quotes may allow a broader search: (swash or (((spat OR span) or sweat) or spate))(-plate or -place ).
• Adding a wildcard symbol may retrieve word variants: "(swash or (((spat OR span) or sweat) or spate))(-plate" or -place")*.
