Hi everyone, what's the difference between ثُعَبَان and أفعى? When do I use one or the other? Could you re-write أفعى with all the harakat? Also, could you give me the plural form of the latter one? And one last question: What's the translation of "viper", "python" and "boa"? I know cobra in Arabic is كوبرا, but does it have any synonyms? Please, if possible write all the harakat and the singular and plural form. I would really appreciate your help. Thanks!
