Showing respect as always aboard charter (8)
I believe the answer is:
reverent
'showing respect as' is the definition.
I can't judge whether this definition defines the answer.
'always aboard charter' is the wordplay.
'always' becomes 'ever' (synonyms).
'aboard' means one lot of letters goes inside another.
'charter' becomes 'rent' (charter can mean to rent or hire).
'ever' put within 'rent' is 'REVERENT'.
Can you help me to learn more?
(Other definitions for reverent that I've seen before include "Showing great respect" , "worshipping" , "Deeply respectful" , "Showing devout awe" , "Showing holy respect" .)
