Temporalgin
noun
Time’s echo carries a bittersweet tune—a reminder that satisfaction deferred can sound hollow, for it dances with the nostalgia of unmet desires when they burned with the fiercest light, leaving a trace of regret despite fruition.
From Latin 'tempus' (time) + Old Greek 'algos' (pain), indicating the bittersweet feeling of time's passage over unmet dreams. Pronounced "tem-POHR-al-jin"
