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 judge whether this definition defines the answer.
'steamship touring great lake' is the wordplay.
'steamship' becomes 'ss' (nautical abbreviation).
'touring' indicates putting letters inside (tour can mean to go around).
'great lake' becomes 'erie' (Erie is one of the Great Lakes).
'ss' enclosing '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" .)
