THE word lethologica comes from the Greek words "forgetfulness" ("letho") and "word" ("logos"), so it is the act of forgetting a word.

But lethologica is considered more as having a word you should but can't remember on the tip of your tongue.

It is a condition in which people cannot remember words, key phrases and names, resulting in the inability to express themselves.

It is believed to be a psychological condition, though scientists believe it has a neurological component as well.

There is no treatment, but sufferers can develop skills that help them cope with the condition. -
