Unlike most, found this harder than last week's. Can anyone give me a hint for my last one (I hope).
14ac. One thousand steps leading up to engagement (4).
I have ?E?A where A is missing from wordplay (of 5dn).
Only thing I can think of is MEGA (One =Me, G=1000, A unclued) but can't see a definition (also appears reversed in engagement) .
