-        Whether to copy input data. Only affects array or Series/Index input,
-        because for other input (e.g. a list) a new array is created anyway.
-        By default, will copy if the input data is a numpy or pandas array.
-        For Series/Index input, a shallow copy of the data is made by default.
+        Whether to copy input data, only relevant for array, Series, and Index
+        inputs (for other input, e.g. a list, a new array is created anyway).
+        Defaults to True for array input and False for Index/Series.
+        Even when False for Index/Series, a shallow copy of the data is made.
         Set to False to avoid copying array input at your own risk (if you
         know the input data won't be modified elsewhere).
+        Set to True to force copying Series/Index input up front.
