thraneen
An insignificant amount; a trifle.

[I]f she wishes to see them at their sport, she has only to make a ring out of a thraneen, and look at them through it, and she will see them in all their bravery with their fox-glove caps and green jerkins, capering to the sound of a bag-pipe, with a lurikeen playing it, and he sitting on a fairy mushroom; but she will never see a stim with that eye again.
Where it comes from
Borrowed from Irish tráithnín (“a stem of dried grass”).
