Definition
The inability to remember or retrieve the right word at the moment you need it — the experience of knowing that a word exists, feeling it just out of reach, and being unable to summon it.
Beyond the definition
Lethologica is a small but maddening experience. The word is there — you've used it before, you know exactly what it means — and yet it won't come. It is language hiding from you in plain sight.
Origin & history
From Greek lethe (forgetfulness, the river of oblivion in Hades) + logos (word) + -ica (condition). Literally: the condition of forgetting words. Lethe, in mythology, was the river whose waters caused complete forgetfulness.

The word was right there. He had used it yesterday. It described exactly what he was trying to say, and it was absolutely, infuriatingly gone.
He could feel the shape of it — how many syllables, roughly, the letter it started with. He could feel its meaning like a thing in a dark room, perfectly real but untouchable.
He gave up and described around it for two minutes. His colleague supplied the word immediately. He said it twice to reclaim it. The relief was disproportionate to the stakes, and entirely genuine.
