need grammar explanation

[jl168]

"君は今日の会議がどんな会議か分かってるのかね?" is extracted from a book.

The meaning is "Did you know what kind of meeting today's meeting was?"

Regarding the phrase "分かってる", I want to ask why "分かる" is changed to "分かって" and why it is then followed by "る".

 

[Toritoribe]

分かってる is the contraction of 分かっている.

Te form
Usage

• With the verbs :
  • いる iru: It means "to be doing". For example: 待っている matte iru: "I am waiting". This is also used in some situations where the English equivalent does not use "to be doing". For example: 知っている shitte iru: "I know", 持っている motte iru: "I have", ここに住んでいる koko ni sunde iru: "I live here". Colloquially, in this form the "i" often disappears, so 待っている matte iru becomes 待ってる matteru and 知っている shitte iru becomes 知ってる shitteru.
