...Just The Facts:
About 1300 angel, aungel (with a hard g as in gem),
replacing earlier angels, angles (with a soft g as in ghost),
a fusion of Old English engel and Latin angelus.
The latter Middle English angel, aungel are a fusion of Old English engel & Old French angele, angel, aungel, from Latin angelus, from Greek ángelos, originally meaning 'messenger'.
The Greek word was a loan translation in the Septuagint of Hebrew mal'akh 'messenger, angel'
& ángaros 'royal mounted courier'.
The Old English engel was a borrowing of Latin angelus. Other Germanic languages made a similar borrowing of the Latin: Old Frisian angel, engel, Old Germanic angil, engil, Old Icelandic engill.
About 1385, borrowed from Old French angélique,
from Latin angelicus, from Greek angelikós,
from ángelos 'angel'.
...The original pronunciation was a hard g & shared understanding with the word angle. In about 1300AD the pronunciation of the word angel (hard g) changed to angel (a soft g). The meanings of messenger/royal mounted courier remained attached.

before 1150 ancleowe;
developed from Old English onclēow (before 800)
cognate with Old High German anchal, enchil which means ankle (modern German enkel),
Old Icelandic okkla (from proto ANKULAN)
