There are words from which you can remove a "chunk", leaving a new word. Like this:
WISHBONE WI SHBO NE WI SHBO NE WI <poof!> NE WI NE WI NE WINE
There are also words that work the other way, for which inserting a "chunk" produces a new word. For example, you can insert the chunk AUTIFI into the word BEER to make BEAUTIFIER.
A "chunk" is a string of consecutive letters. It must consist of at least two letters (no single-letter chunks). It does not need to be a valid English word.
Now, what if I told you there are words into which you can insert a chunk, then remove the same consecutive string of letters, and get a different word from the original word?
What the heck am I talking about?!
I have come up with about 11 examples of this strange phenomenon.
(Too easy? Too hard? Try the counterpart addition paradox.)
Here are my 11 examples:
Start with BEECHES --> insert ES --> obtain BESEECHES --> remove ES --> obtain BESEECH
Start with BEING --> insert ING --> obtain BINGEING --> remove ING --> obtain BINGE
Start with CODER --> insert DE --> obtain DECODER --> remove DE --> obtain DECOR
Start with CODERS --> insert DE --> obtain DECODERS --> remove DE --> obtain DECORS
Start with DEDUCT --> insert ED --> obtain DEDUCTED --> remove ED --> obtain DUCTED
Start with DEFEND --> insert DE --> obtain DEFENDED --> remove DE --> obtain FENDED
Start with PALED --> insert ED --> obtain PEDALED --> remove ED --> obtain PEDAL
Start with POSES --> insert SSES --> obtain POSSESSES --> remove SSES --> obtain POSSE
Start with REDESIGN --> insert ED --> obtain REDESIGNED --> remove ED --> obtain RESIGNED
Start with PAIRED --> insert RE --> obtain REPAIRED --> remove RE --> obtain REPAID
Start with DAUNTED --> insert UN --> obtain UNDAUNTED --> remove UN --> obtain UNDATED
