Angel
Old English engel, ultimately via ecclesiastical Latin from Greek angelos ‘messenger’; superseded in Middle English by forms from Old French angele .
wiktionary
From Middle English angel, aungel, ængel, engel, from Anglo-Norman angele, angle and Old English ænġel, enġel, enċġel(“angel, messenger”), from Proto-West Germanic *angil, borrowed from Latin angelus, itself from Ancient Greek ἄγγελος(ángelos, “messenger”). The religious sense of the Greek word first appeared in the Septuagint as a translation of the Hebrew word מַלְאָךְ (malʾāḵ, “messenger”) or יהוה מַלְאָךְ(malʾāḵ YHWH, “messenger of YHWH”).
Use of the term in some churches to refer to a church official derives from interpreting the "angels" of the Seven churches of Asia in Revelation as being bishops or ministers rather than angelic beings.

etymonline
angel (n.)
"one of a class of spiritual beings, attendants and messengers of God," a c. 1300 fusion of Old English engel (with hard -g-) and Old French angele. Both are from Late Latin angelus, from Greek angelos, literally "messenger, envoy, one that announces," in the New Testament "divine messenger," which is possibly related to angaros "mounted courier," both from an unknown Oriental word (Watkins compares Sanskrit ajira- "swift;" Klein suggests Semitic sources). Used in Scriptural translations for Hebrew mal'akh (yehowah) "messenger (of Jehovah)," from base l-'-k "to send." An Old English word for it was aerendgast, literally "errand-spirit."
Of persons, "one who is loving, gracious, or lovely," by 1590s. The medieval English gold coin (a new issue of the noble, first struck 1465 by Edward VI) was so called for the image of archangel Michael slaying the dragon, which was stamped on it. It was the coin given to patients who had been "touched" for the King's Evil. Angel food cake is from 1881; angel dust "phencyclidine" is from 1968.
