Deeply Moving
Deeply Emotive
い adjective
This is a combination of the words 感慨 meaning "strong feelings" and 深い meaning "deep." Something that makes you feel strong emotions deep down inside is deeply moving.
かんがいぶかい
This is a combination of a jukugo word and an i-adjective. You've learned both of them so just mash them together, with the rendaku making ふ to ぶ, and you've got the reading down pat!
初めて自分の書いたものが出版されるのは、やっぱり感慨深いものがあります。
This is the first time my writing will be published, so of course it’s a deeply moving thing for me.
