Modify widget with borer and adjustable spanner (5,6)
I believe the answer is:
tower bridge
'adjustable spanner' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'modify widget with borer' is the wordplay.
'modify' indicates an anagram (I've seen this in other clues).
'with' is a charade indicator (letters next to each other).
'widget' put after 'borer' is 'borerwidget'.
'borerwidget' with letters rearranged gives 'TOWER BRIDGE'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for tower bridge that I've seen before include "a fixture between two Thames boroughs" , "London landmark" , "river crossing" , "sight in the capital" .)
