# New word from a rotation function

In the Caesar cipher a word is encoded by rotating the letters in the alphabet a given number of times, $$N<26$$. A word is the smallest sequence of phonemes that can be uttered in isolation with objective or practical meaning.

Question. What is the longest word with a sence that is obtained after the rotation function rotN()?

For example, if the is the original word then rot19(the)=max is a new word with a sense. The word's length is 3.

4-letters word: rot23(frog)=cold.

• What counts as a word, exactly? (And I assume N can't be a multiple of 26?)

• Word can be noun, verb... Yes, $N<26$. I updated the question.

• I know the general meaning of "word" -- I mean, for this puzzle, what exactly counts as a word? If there's no clear way to determine what is and isn't a word, the question is opinion-based.

• Answer is a word that can find a word meaning in the Britannica.

wiliwili and corocoro which are inverse under application of ROT6/ROT20

7 letters:

'nowhere' and 'abjurer' are each other's ROT13 inverses

• Did you steal this from the Wikipedia article? I did... purpura ↔ Chechen is another 7 letter listed there either way. Sep 10, 2020 at 23:51

Also seven letters, but not listed in the preexisting answers:

Since for our purposes a word is "the smallest sequence of phonemes that can be uttered in isolation with objective or practical meaning", I propose "myslayd" (put in a place that was thereafter forgotten), which under rot-6 is "Seyrgej" (a man's name).

7 letters : Don't ask the meaning

23->SULPHUR::PRIMERO

22->LEVELER::HARAHAN

22->RISKIER::NEOGEAN

22->TETTERS::PAPPANO

20->MUU-MUU::GOO-GOO

20->POM-POM::JIG-JIG

19->BUMPILY::UNFIBER

18->JIG-JIG::BAY-BAY

16->GOO-GOO::WEE-WEE

16->WEE-WEE::MUU-MUU

14->BAY-BAY::POM-POM

13->ABJURER::NOWHERE

13->CHECHEN::PURPURA

• But I want to know the meaning
