Steamship touring Great Lake for regularly broadcast shows (6)
I believe the answer is:
series
'for regularly broadcast shows' is the definition.
I can't tell whether this defines the answer.
'steamship touring great lake' is the wordplay.
'steamship' becomes 'ss' (nautical abbreviation).
'touring' is an insertion indicator (touring can mean going round).
'great lake' becomes 'erie' (Erie is one of the Great Lakes).
'ss' going around 'erie' is 'SERIES'.
Can you help me to learn more?
(Other definitions for series that I've seen before include "Sequential set" , "Sets in sequence" , "See 8" , "Number of similar things arranged in order" , "Rows" .)
