A plural form of dilemma (archaic or theoretical); a set of difficult choices or situations with no good solutions.
From dilemma + -i as a Latin plural ending, now obsolete. Modern English uses 'dilemmas' instead; 'dilemi' represents an older linguistic convention.
When English borrowed 'dilemma' from Greek, scholars briefly tried the Latin plural 'dilemi'—but it never caught on because English speakers preferred the -s ending!
