polis » poolis, polyis, poleis, polish, poles, polls
poleis » pooleis, polyeis, poleeis, polens, paleis, polemics
poole » pooled, pole, pools
poolla » prolla, doolla, moolla
hole » home, hope, holy

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: ((pol OR ((polle OR pollen) OR (poole OR poolla))) OR (((polis OR poleis) OR poleis) OR hole)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((pol or ((polle OR pollen) or (poole or poolla))) or (((polis or poleis) or poleis) or hole))".
• Adding a wildcard symbol may retrieve word variants: ((pol or ((polle OR pollen) or (poole or poolla))) or (((polis or poleis) or poleis) or hole))*.
