There are two main ways of addressing people:
a using personal names, 'e' is used before the personal name only if it is a short name with no more than one long vowel or two short vowels
e.g. e Mere, e Pita but if the name is longer, such as Wiremu, or the name is not a Māori name, such as Jessica, the name is not preceded by the word 'e'.
e using special terms of address, again 'e' is used before terms of address if they have one long vowel or only two short vowels
e.g. e hine. Here are some terms of address:
used for a friend
used for an intimate friend
used for a girl or young woman
used for a boy or young man
used for an older woman
used for an older man
