The Origin of Criticising or Criticizing
Greek Roots and Suffixes
The word comes from the Greek root krinein, which means “to judge” or “to decide.” This developed into the Greek suffix -izein.
French Influence in the Middle Ages
During the Middle Ages, many Greek words entered the English language through Old French. French spelling changed the -izein suffix to -iser.
Noah Webster’s Reforms
In the late 18th and early 19th centuries, American lexicographer Noah Webster wanted to simplify American spelling. He preferred the original Greek -ize ending because it matched the actual pronunciation of the word.
Meanwhile, British English kept the French-influenced -ise ending. This historical division created the two spellings we use today.
British English vs American English Spelling
Spelling Rules Compared
The choice between criticising and criticizing follows the classic rule for verbs ending in -ise or -ize.
- American English almost exclusively uses -izing for verbs of this type (e.g., organizing, realizing, criticizing).
- British English prefers -ising, though Oxford University Press style (Oxford English Dictionary) accepts -izing as an alternative based on Greek roots. However, everyday British usage heavily favors -ising.
