Per

Per means “by means of”, ?although the English translation may use “by” or “with”. Use this when mentioning tools or methods of transportation. For example:

Per的意思是by?means?of（憑借），在英語里，它可能會被翻譯成 by?或者?with，當提及到工具或者是交通載具時，per就會出現(xiàn)。

• per martelo – with a hammer?? 用錘子

• per tran?ilo – with a knife???????? 用刀子
  

• per buso, per a?to, per trajno, per ?ipo – by bus, by car, by train, by ship????????????????????????? 坐巴士、車、火車、船

Note that per is a preposition and so the following noun does not take the –n ending.

注意：per是一個介詞，所以跟在per后面的介詞并不用加詞尾-n。
