Language is an arbitrary system of sound symbols used by members of social groups to cooperate, communicate and identify themselves. Every country has its own language, which can be used as the country's national identity. Indonesia , has a variety of regional languages that must be preserved, in addition to the Indonesian language, because the diversity of regional languages in Indonesia is a distinctive feature of the Indonesian nation. The Tontemboan language belongs to the language group in the northern part of Indonesia and is a sub-group of the Philippine language family. In essence, the Tontemboan language has two dialectical variations namely Makela'i and Matana'i. It takes effort and hard work to reconstruct documents concerning the Tontemboan language, more specifically regarding frasem in the Tontemboan language with two dialectal variations, namely Makela'i and Matana'i. Frasem patterns in the Tontemboan language are important to study, because frasem as a series of words can be found in every expression, proverb, saying, idiom, collocation, and compound word, all of which can be an interesting picture to master.
