Obvious one, Mog, more than your typical effort? (8)
I believe the answer is:
overtime
'your typical effort?' is the definition.
I can't judge whether this definition defines the answer.
'obvious one mog more' is the wordplay.
'obvious' becomes 'overt' (similar in meaning).
'one' becomes 'i' (Roman numeral).
'mog' becomes 'me' (where the crossword setter is 'Mog').
'more' is a charade indicator (letters next to each other) (some letters added to the previous ones).
'overt'+'i'+'me'='OVERTIME'
'than' acts as a link.
Can you help me to learn more?
(Other definitions for overtime that I've seen before include "Hours worked in excess of usual" , "Extra hours worked" , "Extra hours (at work)" , "Work in excess of fixed period" , "opportunity for supplementing income" .)
