Adam and Ray from steel yard (6)
I believe the answer is:
eldest
This clue might be a double definition.
'adam' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'ray from steel yard' is the second definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'and' is the link.
Can you help me to learn more?
(Other definitions for eldest that I've seen before include "Most aged" , "Most senior of a group" , "Most senior (E, not O)" , "Most advanced in age, led set (anag.)" , "Of greatest age" .)
