Yes, you can use concat :: [[a]] -> [a]:

Prelude> concat ["a","b","c"]
"abc"

Since a String is a type alias for [Char], so "abc" is short for ['a', 'b', 'c']:

Prelude> concat ["a","b","c"] == ['a', 'b', 'c']
True

concat ["a", "b", "c"] will give you the string "abc" which is the same as ['a', 'b', 'c']
