Background: واحد Fish سمک جمع Fish اسماک جمع الجمع Fishes ? The following question is based on the observation that plurals seem to be made from Arabic words in other instances such as خبر ، اخبار ، اخبارات and دوا ، ادویہ ، ادویات , even وجہ ، وجوہ ، وجوہات . While these seem to be accepted (in certain cases as terminology), others such as لواحقین for لاحق / لاحقہ ، لواحق and اکابرین for اکبر ، اکابر seem to be strictly marked as incorrect usages/formation of plurals. In English, fish is used as both singular and plural. However, when referring to more than one species of fish (especially in a scientific context-Biology, Ecology, etc.), fishes is used. Question: What word is or could be used for fishes in Arabic and Urdu?
