Tolerate being bored by Twitter's latest thread (6)
I believe the answer is:
strand
'thread' is the definition.
(strand of material)
'tolerate being bored by twitter's latest' is the wordplay.
'tolerate' becomes 'stand' (synonyms).
'being bored by' is an insertion indicator (inserted letters bore into the word).
'twitter's latest' becomes 'r' (I can't justify this - if you can you should give a lot more credence to this answer).
'stand' enclosing 'r' is 'STRAND'.
Can you help me to learn more?
(Other definitions for strand that I've seen before include "Shore; single thread" , "Leave aground -- length of thread" , "that may be found by the sea" , "Drive aground on shore" , "Old magazine" .)
