One of the most difficult issues in literary translation is striking a balance between keeping authentic to the original work and generating an altogether separate piece that elicits the same feelings as the original piece. Any literary translator will tell you that even a single word may be a source of frustration. After all, a good translation should enable readers from different languages to understand one another's thoughts. In addition to being aware of common words that have multiple translations (such as "love" in Portuguese or Spanish), translators must also be familiar with cultural differences between countries. For example, in English, it is common practice to use "they" instead of "one". This choice can either be made by the translator or the reader; if it is made by the translator, they use gender-neutral pronouns such as "he or she" or "ze/zir". If the reader makes this choice, then "they" becomes necessary. In French, however, it is usual practice to use "ils" for both males and females, so another solution would be needed for translating this into French. The simplest option would be to use "they", but since it is not common practice in French, the translator might want to consider using "les" instead. Even when these choices have been made correctly, certain words or expressions may still cause problems. For example, in English, it is common practice to use "their" instead of "there".
