About the theme

Christmas covers the seasonal register — tree, lights, ornament, stocking, wreath, mistletoe, reindeer, sleigh, carol, gingerbread, nutcracker, tinsel, bauble, candycane, snowman, snowflake. The long compound names anchor every grid; the short ones (tree, holly, ivy, elf, bells, star) hide. A theme that solves with the warmth it carries.
