I was discussing the Twelve Days of Christmas song with my son as a maths exercise. We worked out how many items are received, but I then wondered if pear trees are a singular or plural item.
On day one the line is
My true love gave to me, a partridge in a pear tree
and on every day after it changes to
and a partridge in a pear tree.
As they use the indefinite article, does this mean the recipient also gets twelve pear trees, or could it be the same tree from day one?
