na-adjective
Describes something that evokes strong emotion, often in a positive or heartfelt way. Commonly used for stories, performances, speeches, or experiences.
彼のスピーチはとても感動的だった。
His speech was very moving.
あの映画のラストシーンは感
The final scene of that movie was touching and brought tears to my eyes.
感激 is a stronger, more personal feeling of deep gratitude or excitement, while 感動的 can describe a broader range of moving experiences.
Compound of 感動 (deep emotion) + 的 (-like, -ish). The suffix 的 turns the noun into an adjectival noun meaning 'having the quality of moving one's heart'.
