Japanese is considered to be a language with a lot of ellipsis as a whole. This study explored the types and functions of an abridged sentence ending with high-frequented conjunctive particles like 「te, kara/node, kedo/ga, si, noni, ba/tara」, focusing on the so-called incomplete utterance type abridged sentence. At first, the abridged sentence was set as three types largely, which is specifically as follows. Ellipsis type I is in which the latter sentence is omitted, but the restoration of the latter sentence is possible considering front and back content. Ellipsis type II is the same as ellipsis type I in that the latter sentence is omitted, but the restoration of latter sentence is impossible as it is difficult to specifically be envisaged. And ellipsis type III is a so-called inverted sentence reversing the front sentence and latter sentence, whose position restoration is possible. The function of this ellipsis sentence can be classified as repetition avoiding function, alleviating function, and usage as a sentence-final particle. The repetition avoiding function is what omits the repetition at front and back content and secures the brevity and effectiveness of a sentence to delivered content, bears little direct relation with function of considering the listener. The alleviating function is what omits the expression without directly indicating that giving burden to the other party such as order, refusal and blame etc. and involves in considering the listener. The usage as a sentence-final particle is what indicates the completion of a sentence in a type of incomplete utterance and facilitates the flow of utterance, basically involves consideration of the listener.
