Domestic having one flickering lantern (8)
I believe the answer is:
internal
'domestic' is the definition.
(similar in meaning)
'one flickering lantern' is the wordplay.
'one' becomes 'I' (Roman numeral).
'flickering' is an anagram indicator (I've seen this in other clues).
'lantern' is an anagram of 'nternal'.
'i'+'nternal'='INTERNAL'
'having' acts as a link.
(Other definitions for internal that I've seen before include "Cause of engine power" , "In-house - private" , "Domestic" , "Inside the body" , "Located inward" .)
