Stand shaking under bottom of gable (6)
I believe the answer is:
endure
'stand' is the definition.
(I know that stand can be written as endure)
'shaking under bottom of gable' is the wordplay.
'shaking' indicates an anagram.
'bottom of' indicates one should take the final letters.
The final letter of 'gable' is 'e'.
'under' with letters rearranged gives 'endur'.
'endur'+'e'='ENDURE'
(Other definitions for endure that I've seen before include "Suffer, tolerate" , "Tolerate, put up with" , "Abide" , "brook" , "Put up with - last" .)
