In which I query grammar

[burntcopper]

In this, which I provided icons for two quotes, I'm just wondering - shouldn't it be 'A plague *on* both your houses'? Never heard anyone contract on to o'. o' is always 'of', or 'of the' in English. No matter how far you go back in literary endeavours.

All to do with that fabulous glottal stop we like to utilise. You can't glottal stop or contract an n, that's all. Ts, Fs, and Gs are fair game.
