This paper aims to examine the usage of terms of address which are used among navy officers' wives. Military society is a typical 'rank-based' society. Therefare the members abide by the order based entirely on the rank structure. We can find this phenomenon in the usage of terms of address among officers' wives. They consider seniority of their husbands more significant than solidarity and age relationship with one another. Thus, the wives distinguish the term of address 'samonim' for the wives whose husbands are senior to own husbands by more than 3 years and 'seonbaenim' for the wives whose husbands are senior to their husbands by 1 or 2 years. The important thing here is that they have to use these kinds of terms of address even though the other party is of the same age or younger than them. If wives failed to do so, they will be in a big trouble. This phenomenon seems to take place because of military society's rank-based culture and its distinctive residence culture. An adequate plan for the usage of terms of address among navy officers' wives is needed. This study can be used as useful data for such an effort.
