Problems in translation and interpretation can arise from: insufficient knowledge of one of the languages involved; insufficient knowledge of the subject involved; lack of examples in dictionaries of how specific terms are used; attempted word for word translation; lack of knowledge or understanding of multiple meanings or shades of meaning; ignorance of current usage and "double-entendre". The repercussions of mistranslations range from an amusing faux pas amongst friends; to lost poetic and literary power in the translation of foreign literature; to serious, but unintentional, diplomatic insults.
