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

'stable reliable sort in aa perhaps owing' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'to resolution' is the wordplay.
I cannot quite understand how this works, but
'to' is present in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for tower of strength that I've seen before include "one pulling a lorry by rope?" , "Powerful tractor" , "Person giving support" , "powerful tug?" , "tugboat?" .)
