Husband in step with series of internet postings? (6)
I believe the answer is:
thread
'series of internet postings?' is the definition.
I can't tell whether this defines the answer.
'husband in step' is the wordplay.
'husband' becomes 'h' (abbreviation).
'in' means one lot of letters goes inside another.
'step' becomes 'tread' (synonyms).
'h' inserted inside 'tread' is 'THREAD'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for thread that I've seen before include "Dearth (anag)" , "Prominent spiral part of a screw" , "Connecting line" , "Fine cord of twisted fibers" , "Strand, cord" .)
