Words ending with "-ise" or "-ize"
[edit]The following is a list of common words sometimes ending with "-ise" (en-GB) especially in the UK popular press and "-ize" in American English (en-US) and Oxford spelling (en-GB-oxendict; formerly en-GB-oed) as used by the British Oxford English Dictionary, which uses the "-ize" ending for most of the same words as American English. Commonwealth countries follow British English, except Canada which follows American English spellings more closely.
