Usage notesEdit

• With many terms, a hyphen (-) is used in British English (e.g. co-operate), which is omitted in informal American English (e.g. cooperate). In formal American English the second vowel would be decorated with a diaeresis (coöperate), although this usage is rare and somewhat fussy.
