Colloquially, the term university may be used to describe a phase in one's life: "When I was at university..." (in the United States and Ireland, college is often used instead: "When I was in college..."). In Australia, Canada, New Zealand, the United Kingdom, Nigeria, the Netherlands, Spain and the German-speaking countries university is often contracted to uni. In Ghana, New Zealand and in South Africa it is sometimes called "varsity" (although this has become uncommon in New Zealand in recent years). "Varsity" was also common usage in the UK in the 19th century.[citation needed] "Varsity" is still in common usage in Scotland.
