Has this ever happened to you? Have you ever forgotten a word while you were in the middle of a conversation? Did you feel that it was on the tip of your tongue but oh so elusive?

I have, and it just happened to me today! I was chatting with a friend and completely lost the word I was searching for. It was so annoying,

I discovered there’s a word to describe that phenomenon. It’s lethologica, the technical term for the “tip-of-the-tongue” feeling—that frustrating moment when a specific word or name is on the tip of your tongue but you can’t quite retrieve it from memory.

The term combines lethe (meaning forgetfulness or oblivion, referencing the River Lethe in Greek mythology) and logos (meaning word or speech).

Every language seems to have a way to describe it; in German it’s Es liegt mir auf der Zunge (It’s lying on my tongue.)

While it happens to everyone, lethologica is a complex neurological event involving many factors that aren’t completely understood. Scientists believe one contributing element could be sleep levels, as lethologica tends to happen more often to those who are tired. Other factors might include how well the memory was encoded (the base memory of the word) and interference from other memories, which can cause confusion.

Studies have also found a positive correlation with age. Older adults might experience lethologica up to once a day, while younger adults experience it around once a week. The average native English-speaking American adult knows around 42,000 dictionary words; it’s only natural that some are forgotten from time to time.

The most common resolution for the failure to recall a specific word is to NOT think about it, which is often when the word suddenly “pops up” out of nowhere. This is referred to as a spontaneous resolution or one in which the state resolves itself.
