+1... speaking as someone who knows quite a bit about english grammar, that's a hard question you pose there. *why not ask on the english site?*

<p>Just as 已经 means "already" and emphasizes the sense of the completed action particle 了, 曾经 means "once" and emphasizes the sense of 过. I disagree with Bob that 曾经 means already here; in general "once" or "ever" is a better translation. I would render your sentence as "I once studied two years of Chinese in Beijing."</p>

<p>It means 'already', to add emphasis to the sentence - 'he already studied Mandarin in Beijing for two years'</p>

<p>In this sentence:</p>

<blockquote>
  <p>他曾经在北京学过两年汉语。</p>
</blockquote>

<p>what's the role of 曾经? I understand that 过 already implies that the action happened in the past.</p>

<past-tense>
What's the role of 曾经 in 他曾经在北京学过两年汉语?
# What's the role of 曾经 in 他曾经在北京学过两年汉语?

(Asked by: username_0 on 2012-01-14)

In this sentence:

> 他曾经在北京学过两年汉语。

what's the role of 曾经? I understand that 过 already implies that the action happened in the past.

曾经 is more equivalent to "once" in English as in the sentence

> Once we were the best friends.

It is used to:

> 1. express the fact the sentence is talking about happened in the past.
> 2. if the predicate verb is a durative verb\*, express that fact can't be experienced(经=experience) by the speaker(doesn't last) any more.   
>    , the speaker implies that the status is different now. In this case, it means "used to" as in the sentence "*I used to be a kind man(implies now I am not)*." For your example, the speaker implies that he is not studying Chinese in Bejing now.

\*By "durative verb", I mean the action expreesed by that verb can last for a long time. For example, "study, like, look, be, work,feed, etc.". These verbs can be used in the progress tense in English(-ing form). Some other verbs can not, such as "hear of, see, kick, etc." You can't say " I am hearing of a terrible story", while you can say" I am listening to a terrible story".

Can someone tell me the right grammar term if I am wrong?

It means 'already', to add emphasis to the sentence - 'he already studied Mandarin in Beijing for two years'
