The comparative form of 'blessed,' meaning more blessed or fortunate than something else.
From Old English 'bletsian' (to consecrate) plus the comparative suffix '-er.' Though 'more blessed' is more standard modern usage, 'blesseder' appears in older texts as a valid comparative.
Most English speakers say 'more blessed' today, but 'blesseder' shows how English used to regularly add '-er' to almost any adjective—language naturally streamlined this over centuries.
