[Middle English referren, from Old French referer, from Latin referre : re-, re- + ferre, to carry; see bher-1 in the Appendix of Indo-European roots.]
refer·a·ble (rĕfər-ə-bəl, rĭ-fûr-) adj.
Usage Note: Some people consider the phrase refer back to be redundant, since refer contains the prefix re–, which was brought into English from Latin and originally meant "back." But such an argument is based on what linguists call the "etymological fallacy"—the assumption that the meaning of a word should always reflect the meanings of the words, roots, and affixes from which it was derived. In fact, most words change their meanings over time, often to the point where their historical roots are completely obscured. Such change is natural and usually goes unnoticed except by scholars. We conduct inaugurations without consulting soothsayers (augurs), and we don't necessarily share bread (pānis in Latin) with our companions. In fact, refer is quite often used in contexts that don't involve the meaning "back" at all, as in The doctor referred her patient to a specialist or Please refer to this menu of our daily specials. As for refer back, the Usage Panel's position has shifted dramatically over the years. In 1995, 65 percent of the Panel disapproved of this construction, but by 2011, 81 percent accepted it in the sentence To answer your question it is necessary to refer back to the minutes of the previous meeting. In such cases, where the "back" meaning of re– has largely disappeared, adding back can provide useful semantic information, indicating that the person or thing being referred to has been mentioned or consulted before. The Panel remains somewhat less tolerant of constructions like revert back, in which the verb retains the sense "back" as part of its meaning: in 2011, 67 percent accepted revert back in the sentence After his divorce he seemed to revert back to his adolescence. In this context, back may simply be used to provide emphasis, perhaps suggesting a greater step backward than the verb by itself would. In any case, the prevalence of phrases that combine back and words prefixed with re– indicates that such constructions are a robust feature of English, even if they do appear to be logically redundant.
