History and Etymology for diadem

Middle English diademe "monarch's crown, crownlike headdress," borrowed from Anglo-French, borrowed from Latin diadēma "ornamental headband, crown," borrowed from Greek diadēmat-, diádēma "headband, band wrapped around the headdress by Persian monarchs," from diadē-, variant stem of diadéō, diadeîn "to bind on either side, bandage" (from dia- dia- + déō, deîn "to bind, tie") + -mat-, -ma, resultative noun suffix; Greek déō, deîn probably going back to a zero-grade form (*dh1-i̯é-?) of the Indo-European verbal base *deh1- "tie, bind," whence also Sanskrit ā́-dhyati "(s/he) binds," Hittite tiya "bind!"; from a full grade *deh1- Greek édēsa "(I) bound," Sanskrit dāman-, dā́ma "cord, fetter"
