‘Opa, the usual greeting, is appropriate for any hour of day or night. Good morning and good evening are not true Umu terms. ‘Opa is also used for leave-taking. Usually the greeting is said first, then the person’s name or title.
‘Opa & ‘opawu – it is good, is also used where such statements would be appropriate in English. In this sense, both are interchangeable.
Any woman old enough to be one’s mother may be addressed mariwme. She may call any young man ‘arawme. Unmarried women use the term when speaking to younger men or boys – those young enough to be her son.
Older people are often reluctant to give their names. They prefer using a social title or having someone else tell their name. Younger people are used to giving their names at school and work.
