non-com 的词源

也可以写作 noncom，到1817年时，这个词是 non-commissioned (officer) 的缩写。

The "non-coms" — non-commissioned, meaning, not non compos; though evil-minded high privates declare it might well mean that — have assigned to them an upper cabin, with staterooms, over the quarters of the officers, in the after-part of the ship. [James K. Hosmer, "The Color-Guard," Boston, 1864]

“非委任军官”——也就是 non-coms，并不是 non compos；尽管一些心怀不轨的高级士兵可能会认为这也许是另一种意思——他们被分配到了船后部军官宿舍上方的一个上层舱室，里面有卧室。[詹姆斯·K·霍斯默，《护色队》，波士顿，1864年]
