pleonastically

In talk of 'feeling a pain' the word 'feel' is being used pleonastically.

The repeated negation is used pleonastically for emphasis.

Even to this rule there are exceptions, and one of these is in the case of a tarn which I shall call, pleonastically, Little Loch Beg.

(May imply "I'm going much farther south than you might think if I didn't stress the southerliness of my destination"; but such phrasing is also sometimes-and sometimes jokingly-used pleonastically when simply "south" would do; it depends upon the context, the intent of the speaker/writer, and ultimately even on the expectations of the listener/reader.)
