/and"awr"/ , conj.
(used to imply that either or both of the things mentioned may be affected or involved): insurance covering fire and/or wind damage.
Usage . The combination AND/OR is used primarily in business and legal writing: All dwellings and/or other structures on the property are included in the contract. Because of these business and legal associations, some object to the use of this combination in general writing, where it occasionally occurs: She spends much of her leisure time entertaining and/or traveling. In such writing, either AND or OR is usually adequate. If a greater distinction is needed, another phrasing is available: Would you like cream or sugar, or both?
