Greek in time leading people attending Mass (9)
I believe the answer is:
aggregate
'mass' is the definition.
(I know that mass can be written as aggregate)
'greek in time leading people attending' is the wordplay.
I cannot really understand how this works, but
'greek' could be 'gr' (abbreviation for Greek) and 'gr' is present in the answer.
'time' could be 'age' (an age is a period of time) and 'age' is present in the remaining letters.
'attending' could be 'at' (e.g. at school means attending school) and 'at' is found in the answer.
The remaining letters 'ge' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for aggregate that I've seen before include "Solid rock" , "Sum of many heterogenous things taken together" , "All - broken stone put in cement" , "Accumulate into total" , "A whole formed by combining several elements" .)
