Glory at the Front tied to army spirit (5)
I believe the answer is:
ghost
'army spirit' is the definition.
'ghost' can be an answer for 'spirit' (spirit can mean a ghost). I'm unsure of the 'army' bit.
'glory at the front tied' is the wordplay.
'at the front' suggests taking the first letters.
'tied' becomes 'host' (I can't justify this - if you can you should give a lot more credence to this answer).
The first letter of 'glory' is 'g'.
'g'+'host'='GHOST'
'to' is the link.
Can you help me to learn more?
(Other definitions for ghost that I've seen before include "author for someone" , "who has a haunting act?" , "Writer who gives the credit of authorship to someone else" , "Spirit of the dead" , "someone without much presence" .)
