"Long time past, my heroes," Gawaine was saying, "before ourselves were born or thought of, there was a beautiful grandmother at us, called Igraine."
"So he sent our Grandfather a letter which bid him to stuff him and garnish him, for within forty days he would fetch him out of the strongest castle that he had!" "There were two castles at him," said Agravaine haughtily. "They were the Castle Tintagil and the Castle Terrabil."
The construction I'm curious about is the one in a grandmother at us and two castles at him.
Can these be identified as some sort of Gaelic influence? For example, is there a construction in Gaelic which, if translated literally word-for-word into English, would have that form?
