Support band almost sincere: songs lacking content (5)
I believe the answer is:
truss
'support band' is the definition.
'truss' can be an answer for 'band' (thesaurus). I'm not certain of the 'support' bit.
'almost sincere songs lacking content' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'sincere' becomes 'true ' (associated in meaning).
'lacking content' means to remove the middle letters (the content of the word is emptied out).
'songs' with its centre removed is 'ss'.
'true' with its last letter taken off is 'tru'.
'tru'+'ss'='TRUSS'
Can you help me to learn more?
(Other definitions for truss that I've seen before include "Structure supporting a roof" , "Support - bundle - cluster" , "Supporting framework" , "Surgical appliance" , "Wing beam of a plane" .)
