Beams and walks in a pompous way (6)
I believe the answer is:
struts
This clue could be a double definition.
'beams' is the first definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe there's a link between them I don't understand?
'walks in a pompous way' is the second definition.
'struts' can be an answer for 'walks' (strut is a kind of walk). I'm not sure about the 'in a pompous way' bit.
'and' is the link.
Can you help me to learn more?
(Other definitions for struts that I've seen before include "Walks proudly like farmyard rooster" , "Walks proudly with support braces" , "parades with conscious pride" , "Walks in pompous self-satisfied way" , "Walks proudly like peacock" .)
