The Origin of Behavioral or Behavioural
The root word behaviour/behavior comes from Old French behaver, meaning “to conduct oneself.” When English spelling began to standardize, American English simplified many words by removing the extra -our. British English kept the original form. That’s why we now have behavioral (US) and behavioural (UK). The spelling difference exists because of regional spelling reforms, not meaning.
