Webster’s 1828 dictionary had only -or and is given much of the credit for the adoption of this form in the United States. By contrast, Johnson’s 1755 (pre-US independence and establishment) dictionary used -our for all words still so spelled in Britain (like colour), but also for words where the u has since been dropped: ambassadour, emperour, errour, governour, horrour, inferiour, mirrour, perturbatour, superiour, tenour, terrour, tremour. Johnson, unlike Webster, was not an advocate of spelling reform, but chose the spelling best derived, as he saw it, from among the variations in his sources.
Nope.
Although unjerk, spelling reform and standardisation is very necessary for english.
