Priest regularly dropping bits of éclair (3)
I believe the answer is:
eli
'priest' is the definition.
(biblical figure)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for eli that I've seen before include "Old Testament high priest" , "Distort then untruth to get a Biblical character" , "Highest priest at Shiloh" , "- Whitney invented the cotton gin in seventeen ninety three" , "Religious character" .)
