Old people with average ways (5)

Ross

I believe the answer is:

medes

I'm a little stuck... Click here to teach me more about this clue!

'old people' is the definition.
(people of the Median Empire)

'with average ways' is the wordplay.
'with' means one lot of letters go next to another.
'average' becomes 'med' (I can't explain this - if you can you should believe this answer much more).
'ways' becomes 'es' (east and south - two directions).
'med' next to 'es' is 'MEDES'.

Can you help me to learn more?
