Lethologica
noun /ˌlɛθəˈlɒdʒɪkə/ — The tip-of-the-tongue feeling — when the right word escapes you.
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.

Fictional scene
Waiting for the Right Word
An adult sits at a piano, hands hovering above the keys in anticipation, but remaining perfectly still and silent.
The anticipation of music, currently held in stillness, mirrors the experience of knowing a word exists but being unable to retrieve it. It is the feeling of being right on the edge of expression, yet unable to summon the sound.
