of words. Minor systematic difference which occur between Australian and British spelling are as follows: Words often ending in eable in British English end in able in Australian English. Therefore, Australian English favours livable over liveable, sizable over sizeable, movable over moveable, etc., although both variants are acceptable. Words often ending in eing in British English end in ing in Australian English. Therefore, Australian English favours aging over ageing, or routing over routeing, etc., although both variants are acceptable. Words often ending in mme in British English end in m in Australian English. Therefore, Australian English favours program over programme (in all contexts) and aerogram over aerogramme, although both variants are acceptable. Similar to Canada, New Zealand and the United States, (kilo)gram is the only spelling. Other examples of individual words where the preferred spelling is listed by the Macquarie Dictionary as being different from current British spellings include analog as opposed to analogue, guerilla as opposed to guerrilla, verandah as opposed to veranda, burqa as opposed to burka, pastie (noun) as opposed to pasty, neuron as opposed to neurone, hicup as opposed to hicough, annex as opposed to annexe, raccoon as opposed to racoon etc. Unspaced forms such as onto, anytime, alright and anymore are also listed as being equally as acceptable as their spaced counterparts. There is variation between and within varieties of English in the treatment of -t and -ed endings for past tense verbs. The Macquarie Dictionary does not favour either, but it suggests that leaped, leaned or learned (with -ed endings) are more common but spelt and burnt (with -t endings) are more common. Different spellings have existed throughout Australia's history. What are today regarded as American spellings were popular in Australia throughout the late 19th and early 20th centuries, with the Victorian Department of Education endorsing them into the 1970s and The Age newspaper until the 1990s. This influence can be seen in the spelling of the Australian Labor Party and also in some place names such as Victor Harbor. The Concise Oxford English Dictionary has been attributed with re-establishing the dominance of the British spellings in the 1920s and 1930s. For a short time during the late 20th century, Harry Lindgren's 1969 spelling reform proposal (Spelling Reform 1 or SR1) gained some support in Australia and was adopted by the Australian Teachers' Federation.
