Poetry texts are amongst many texts that are said to be difficult to translate. Literary works are the most challenging to translate. This is because each poet has a different way of using words or figures of speech. It is difficult to conform to these specific words, thoughts or emotions of the poet. Moreover, each language has its own syntactic structure, sounds, metaphorical expressions and poetic structure different from another. There are words that have no literal translation to another language. This is the reason as to why many people feel that poetry texts are the most difficult to translate.
