Call which people hope to make with letters? (4,4)
I believe the answer is:
last post
'call which people hope' is the definition.
'last post' can be an answer for 'call' (I've seen this before). I am not certain of the remainder of the definition.
'make with letters?' is the wordplay.
'make with' becomes 'last' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'letters?' becomes 'post' (letters in the mail or post).
'last'+'post'='LAST POST'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for last post that I've seen before include "notes we hear on Armistice Day" , "Bugle call at night or at funeral" , "ceremonial piece of music" , "Army bugle call at sunset and funerals" , "Military bugle call at funerals and sunset" .)
