On the true true

I asked Meronym if the Abbess spoke true, when she said the Hole World flies round the sun, or if the Men o' Hilo was true sayin' the sun flies round the Hole World.

Abbess is quite correct, answered Meronym.

Then the true true is different to the seemin' true? said I.

Yay, an' it usually is, I mem'ry Meronym sayin', an' that's why true true is presher'n'rarer'n diamonds.
