This is the 10th most frequent Chinese word.
新
"New"
Here, 新 (xīn) is used as an adjective to describe something that is newly acquired or unused, emphasizing the state of being new.
我买了一件新衣服。
I bought a new piece of clothing.
In this sentence, 新 (xīn) modifies 学到 to indicate the recency of acquiring knowledge, showing an adverbial usage to denote something recent.
这是我新学到的知识。
This is the knowledge I recently learned.
新 (xīn) again acts as an adjective here, describing 'place' to emphasize that the location is different and recently settled upon.
