As the former director of the Australian National Dictionary Centre at The Australian National University, the lexicographer was surprised by the word schmick, one he had never heard before.

Schmick is just one of 6000 new words and phrases, including words from more than 100 Indigenous languages, that have been officially recognised in the second edition of the Australian National Dictionary published on Tuesday August 23.

Babyccino, battered sav, grey nomad, and carry on like a pork chop are among some others. So too are "doing a Bradbury" and "straight to the pool room".

New words and terms from the ACT include: booner (a person regarded as uncultured or unsophisticated; a bogan), ex-govie (a privately owned dwelling originally built and leased by the government), and Jennings German (a German migrant tradesman recruited to Canberra in the 1950s to work for AV Jennings).

Other words directly related to the ACT include Canberran (a resident of Canberra, or a person born in Canberra) and bush capital (a name for Canberra).

"The dictionary shows how Australian words tell us much about Australian history and about Australian values and attitudes," Dr Moore said.

"The Australian National Dictionary is the essential cultural and historical document that maps the words that define who we are, where we have come from and what we value."

It has been 28 years since the first edition was published and Dr Moore said it was interesting to note that in the first edition no words were labelled offensive.

"It shows how changes in attitude towards language have occurred."

The dictionary now traces the history of 16,000 words and phrases, including slang and regional words, back to their original sources, including books, newspapers and diaries.

Oxford University Press managing director Peter van Noorden said the new edition was a crucial record of Australian culture and identity.

"It is vital that these words be recorded," Mr van Noorden said.

"If language is a definer of nationhood and the character of a people, then this new edition illustrates what it means, in words, to be Australian."

The lavishly bound, two-volume set was published by Oxford University Press Australia and New Zealand and compiled by the Australian National Dictionary Centre at The Australian National University.

As Dr Moore says, "it's the schmickest dictionary about". One destined to go straight to the pool room.
