Latin praise? Attempt to keep Latin manner up (6)
I believe the answer is:
gloria
'latin praise?' is the definition.
The definition suggests a singular noun which matches the answer.
'attempt to keep latin manner up' is the wordplay.
'attempt' becomes 'go' (go is a kind of attempt).
'to keep' indicates putting letters inside.
'latin' becomes 'l'.
'manner' becomes 'air' (air can mean someone's manner or character).
'up' shows that the letters should be reversed in order (in down clue: letters go upwards).
'air' written backwards gives 'ria'.
'go' enclosing 'l' is 'glo'.
'glo'+'ria'='GLORIA'
Can you help me to learn more?
