Millions in shadow of Sri Lankans? (5)
I believe the answer is:
tamil
'of sri lankans?' is the definition.
I can't judge whether this definition defines the answer.
'millions in shadow' is the wordplay.
'millions' becomes 'm' (abbreviation).
'in' is an insertion indicator.
'shadow' becomes 'tail' (both can mean to follow someone).
'm' going into 'tail' is 'TAMIL'.
Can you help me to learn more?
(Other definitions for tamil that I've seen before include "Language of southern India and Sri Lanka" , "S. India/Sri Lankan person, tongue" , "Dravidian people of India and Sri Lanka" , "Perhaps Indian" , "Member of South Indian people" .)
