What is the grammar pattern in "藏语呢我是略知一二"？ I was watching a show and one guy said &quot;藏语呢我是略知一二&quot;. Now I'm having a little bit of trouble understanding the grammar pattern for this sentence, especially with the use of the &quot;是&quot;. I'm not entirely sure why the &quot;是&quot; is place where it is, as I would assume the subject would be the idiom &quot;略知一二&quot;, which I've only ever watched or read them to be used as an adjective- so wouldn't that mean you would have to use an adverb like &quot;很&quot;?
So my question is: What is the grammar pattern in this sentence?
Thanks everyone
It is a [topic + comment] sentence
Topic: '藏语呢' -- 'about the Tibetan language'
Comment: '我是略知一二(的)' -- 'I am slightly familiar with'
我是略知一二(的) is a relative phrase that gives a description/ comment on the topic/ object 藏语
SVO: '我對藏语略知一二' -- ''I am slightly familiar with the Tibetan language'
More example:

SVO: 我是不会再去这间餐厅的


T/P: 这间餐厅 我是不会再去的

in &quot;我 是 (XXX) 的&quot;, (XXX) describes &quot;我&quot;

SVO: 我不会再去这间餐厅了


T/P: 这间餐厅 我不会再去了

&quot;了&quot; is a final particle
