The Wikipedia page includes the English equivalents of Schadenfreude.
- Roman holiday
- Morose delectation
Little-used English words synonymous with schadenfreude have been
derived from the Greek word epichairekakia (ἐπιχαιρεκακία). Nathan
Bailey's 18th-century Universal Etymological English Dictionary, for
example, contains an entry for epicharikaky that gives its etymology
as a compound of ἐπί epi (upon), χαρά chara (joy), and κακόν kakon
(evil). A popular modern collection of rare words, however, gives its
spelling as "epicaricacy".
An English expression with a similar meaning is 'Roman holiday', a
metaphor taken from the poem "Childe Harold's Pilgrimage" by George
Gordon, Lord Byron, where a gladiator in Ancient Rome expects to be
"butcher'd to make a Roman holiday" while the audience would take
pleasure from watching his suffering. The term suggests debauchery and
disorder in addition to sadistic enjoyment.
Another phrase with a meaning similar to Schadenfreude is "morose
delectation" ("delectatio morosa" in Latin), meaning "the habit of
dwelling with enjoyment on evil thoughts". The medieval church taught
morose delectation as a sin. French writer Pierre Klossowski
maintained that the appeal of sadism is morose delectation.
An English word of similar meaning is "gloating", where "gloat" is
defined as "to observe or think about something with triumphant and
often malicious satisfaction, gratification, or delight" (gloat over
an enemy's misfortune).
The internet slang term "lulz" (A variation of LOL) has acquired the
connotation of fun or amusement at another person's expense,
especially in regard to trolling behavior.
