中英語のjunke、船の古いケーブルやロープ、おそらく古フランス語のjuncから、ラテン語のjuncus、reed、corduroyに由来し、語源的にはjunketと同じ。
ジャンク 中国の帆船ポルトガル語のjuncoから、マレー語のjong、ボート、大型船、最終的には中国語のchuan、船から。
New settlers (who should always be here as early in the spring as possible) begin to cut down the wood where they intend to erect their first house. As the trees are cut the branches are to be lopped off, and the trunks cut into lengths of 12 or 14 feet. This operation they call junking them; if they are not junked before fire is applied, they are much worse to junk afterwards.
