reread
From re- + read. read comes from Middle English reden, from Old English rǣdan (“to counsel, advise, consult; interpret, read”), from Proto-West Germanic rādan, from Proto-Germanic rēdaną (“advise, counsel”), from Proto-Indo-European Hreh₁dʰ- (“to arrange”). Cognate with Scots rede, red (“to advise, counsel, decipher, read”), stq räide (“to advise, counsel”), West Frisian riede (“to advise, counsel”), Dutch raden (“to advise; guess”), German raten (“to advise; guess”), Danish råde (“to advise”), Swedish råda (“to advise, counsel”), Persian رده (“to order, to arrange, class”). In West Germanic the verb had a sense “interpret”, which developed further into “interpret letters” in English and “interpret by intuition, guess” on the continent. Compare rede.
