Bimonthly is a problem word, and you should treat it that way from the start. Real people use it in two opposite ways, and both show up in print.

Bimonthly is a problem wordBimonthly 是一個麻煩的詞, and而且 you should treat it that way from the start你從一開始就該這樣看待它 Real people use it in two opposite ways真實世界裡的人會用它表示兩種相反的意思, and而 both show up in print兩種用法都會出現在印刷品裡

One meaning: happening every two months. A bimonthly magazine then comes out six times a year — January, March, May, and so on. The other meaning: happening twice each month, for example on the 1st and the 15th.

One meaning其中一個意思是: happening every two months每兩個月發生一次 A bimonthly magazine那麼一本雙月雜誌 then comes out six times a year一年就會出刊六次 — January, March, May, and so on一月、三月、五月，依此類推 The other meaning另一個意思是: happening twice each month每個月發生兩次, for example on the 1st and the 15th比如1號和15號

You cannot know which one is meant from the word alone. You have to look at the rest of the sentence, a calendar, or just ask 'How many times a year?' Writers who want to be clear often avoid bimonthly and say 'every two months' or 'twice a month'. Magazines sometimes print 'bimonthly (six issues a year)' to lock it down.

You cannot know which one is meant from the word alone單看這個詞你沒辦法知道是哪一個意思 You have to look at你得看 the rest of the sentence, a calendar, or just ask 'How many times a year?'句子的其他部分、日曆，或乾脆問「一年幾次？」 Writers who want to be clear想表達清楚的作者 often avoid bimonthly常常會避開 bimonthly and而 say 'every two months' or 'twice a month'改說「每兩個月」或「一個月兩次」 Magazines sometimes print雜誌有時候會印上 'bimonthly (six issues a year)'「bimonthly（一年六期）」 to lock it down來把意思鎖死

Though actually, the mess is old and has not been solved. English took bi- from Latin for 'two', but 'two' can mean 'every two' or 'two per'. The same fight sits on biweekly. If a form, a contract, or your homework uses bimonthly, do not guess.

Though actually不過老實說, the mess is old and has not been solved這個混亂由來已久，而且從沒被解決過 English took bi- from Latin for 'two'英文的 bi- 是從拉丁文的「二」來的, but但 'two' can mean 'every two' or 'two per'「二」可以是「每二」也可以是「每...二次」 The same fight sits on biweekly同樣的爭議也發生在 biweekly 身上 If a form, a contract, or your homework uses bimonthly如果一份表格、合約，或你的作業用到 bimonthly, do not guess千萬不要用猜的
