Typoglycemia is a neologism given to a purported recent discovery about the cognitive processes behind reading written text. The word does not refer to any actual medical condition related to hypoglycemia. The word appears to be a portmanteau of "typo", as in typographical error, and "hypoglycemia". It is an urban legend/Internet meme that appears to have an element of truth to it.

The legend, propagated by email and message boards, purportedly demonstrates that readers can understand the meaning of words in a sentence even when the interior letters of each word are scrambled. As long as all the necessary letters are present, and the first and last letters remain the same, readers appear to have little trouble reading the text.
