to trust that what someone says is true
誰かの言っていることを信じる (dareka no itte iru koto o shinjiru)
"I’ll take your word for it since you were there."
"あなたがそこにいたので、私はあなたの言葉を信じます。" (anata ga soko ni ita node, watashi wa anata no kotoba o shinjimasu)
to become more ill
to work hard and continuously
someone who is very dear and loved deeply
to study intensely
to attack someone's most vulnerable point
directly involved in the most active or dangerous part of so...
