This is a variation of Abracadabra.

The words "notion", "thought" and "devolved" share a similar pattern.

Each of the three words consist of three groups of letters where the third group is formed by writing the first group in reverse order and the second group of letters is between them – and, each of the three groups consists of 2 or more letters.

None of the words can be palindromes, and:
None of the words can be plurals or proper nouns.

What is the longest word satisfying all the above conditions ?

Bonus Question:

For an extra challenge, find the longest word satisfying all the given conditions with the added proviso that none of the words can start with DE or RE.

The English word "supercalifragilisticexpialidocious" is 34 letters in length.  The online dictionary 'Dictionary.com Unabridged'  (based on the Random House Dictionary, (c) Random House, Inc 2012) categorizes it as an adjective and gives the definition that it is "used as a nonsense word by children to express approval or to represent the longest word in English".

(1) the word can be divided into three groups where the letters of the first group and third group are in reverse order of each other and each group consists of 2 or more letters:
  group 1: SU
  group 2: PERCALIFRAGILISTICEXPIALIDOCIO
  group 3: US
(2) the word is not a palindrome, and
(3) the word is not a plural or proper noun
