In Tennyson's poem "The Lady of Shalott" there is the following verse:
There she weaves by night and day
A magic web with colours gay.
She has heard a whisper say,
A curse is on her if she stay
To look down to Camelot.
She knows not what the curse may be,
And so she weaveth steadily,
And little other care hath she,
The Lady of Shalott.
Now part of her curse, as I understand it, is that she cannot leave Shalott, and cannot look out the windows because she may see Camelot. So why is it stay? She has to stay! Shouldn't it be stray? As in her eyes stray to look out the window to Camelot?
