from roundabout (engaging in circumlocution, long-winded)+ -ation
“…At dinner fair Adelaide brought up a chicken
A bird that she never had met with before;
But, seeing him, scream’d, and was carried off kicking,
And he bang’d his nob’gainst the opposite door.
To finish my tale without roundaboutation,
Young master and missee besieged their papa;
They sung a quartetto in grand blubberation
The Stranger cried Oh! Mrs. Haller cried Ah!
Though pathos and sentiment largely are dealt in,
I have no good moral to give in exchange…”

Or, The New Theatrum Poetarum
