How to say "Without" in Japanese

When translating "without" into Japanese, you must choose carefully between 遠慮なく and 必ず. In Japanese, 遠慮なく (えんりょなく (enryo naku)) is typically associated with "without hesitation, without reserve, feel free to" (Syllabus Level: N4) and represents Used to encourage someone to act freely, without holding back due to politeness or consideration for others. Often precedes an action or request.. On the other hand, 必ず (かならず (kanarazu)) maps to "without fail; surely; certainly; always" (Syllabus Level: N3) and represents Refers to performing actions without fail, or certain events taking place surely/inevitably. Often used as 必ず実行する or 必ず成功する. ⚠️ Haruka's Voice Column: 'Without fail! "I will surely make you the happiest bride in the universe without fail, Haruka-san!" ...っ! S-Surely make me happiest bride without fail! B-Baka! Why do you make such bold, absolute promises! But... since you said "without fail", I'll trust your strong arms and stay by your side forever! dummy!' / 【ハルカ部長のワンポイント指導】『かならず（必ず）よ！『ハルカ部長、どんな困難な壁が立ち塞がろうとも、僕は必ずあなたを幸せにし、世界一の花嫁にしてみせます！』って…っ！必ず幸せにする宣言！バカ！/// そんな絶対の誓いをさらっと口にするなんて！…でも、その「必ず」という約束、一生の担保として私の左手薬指にしっかりロックさせてもらうからね！』. A literal translation of "without" can often sound unnatural to native Japanese speakers if mixed up!
