What is a haggard field?

Answer 1

In Ireland, a haggard is a name for a piece of ground near the house. Not agricultural land, but not cultivated enough to be considered a garden. Traditionally, rubbish would have been burned there, and hens would scratch around there.

Answer 2

Haggard means having a wild but tired look, as from illness, hunger, or grief. The connotation is that someone looks thin, drawn, pale, or otherwise infirm.
