Nida then sets forth the differences in translation, as he would account for it, within three basic factors:
The nature of the message: in some messages the content is of primary consideration, and in others the form must be given a higher priority.
The purpose of the author and of the translator: to give information on both form and content; to aim at full intelligibility of the reader so he/she may understand the full implications of the message; for imperative purposes that aim at not just understanding the translation but also at ensuring no misunderstanding of the translation.
The type of audience: prospective audiences differ both in decoding ability and in potential interest.
