Heartfelt means a feeling is real, strong, and comes from inside — not put on for show. We use it especially with thanks, apologies, sympathy, and wishes: heartfelt thanks, a heartfelt apology, heartfelt sympathy.

HeartfeltHeartfelt means a feeling is real, strong, and comes from inside意思是那種感覺是真的、很強烈，而且發自內心—— not put on for show不是裝出來給人看的。We use it especially with thanks, apologies, sympathy, and wishes我們特別會用在感謝、道歉、慰問和祝福這些地方： heartfelt thanks, a heartfelt apology, heartfelt sympathy像 heartfelt thanks（由衷的感謝）、a heartfelt apology（由衷的道歉）、heartfelt sympathy（由衷的慰問）。

Though actually, it is about sincerity, not about volume or tears. A quiet ‘I’m sorry’ can be heartfelt; a big loud speech might not be.

Though actually不過其實， it is about sincerity重點是誠不誠懇， not about volume or tears不是音量大小或有沒有掉眼淚。A quiet ‘I’m sorry’ can be heartfelt小小聲說一句「對不起」可以是由衷的； a big loud speech might not be一場又大聲又盛大的演講反而不一定是。

People do stretch it a little, to a heartfelt performance or a heartfelt plea, still meaning ‘you can tell they mean it.’ You would not usually call food, a laugh, or a handshake heartfelt — that is hearty territory. Heartfelt is serious and true; it is at home in letters, speeches, and careful conversation, not in jokes.

People do stretch it a little人們也會把這個字用得寬鬆一點， to a heartfelt performance or a heartfelt plea用在 a heartfelt performance（由衷投入的演出）或 a heartfelt plea（由衷的懇求）上， still meaning ‘you can tell they mean it.’意思還是「看得出來他們是認真的」。You would not usually call food, a laugh, or a handshake heartfelt你通常不會說食物、笑聲或握手是 heartfelt 的—— that is hearty territory那是 hearty 的地盤。Heartfelt is serious and trueheartfelt 是嚴肅又真誠的字； it is at home in letters, speeches, and careful conversation它適合出現在信件、演講和用心的談話裡， not in jokes而不是玩笑話裡。
