How to say "Old" in Japanese

When translating "old" into Japanese, you must choose carefully between ふるい and 老獪. In Japanese, ふるい (ふるい (furui)) is typically associated with "old (not for people)" (Syllabus Level: N5) and represents An い-adjective. Used for objects, buildings, or things that have existed for a long time. Not used for the age of people. Opposite of 新しい. On the other hand, 老獪 (ろうかい (rōkai)) maps to "old and cunning; wily; astute (often implying negative conniving)" (Syllabus Level: N1) and represents 経験を積んでいて、物事の裏をかくなどずる賢い様子を表す。良い意味ではあまり使われず、策略的で手強い人物を指す。Describes someone who is experienced and shrewd, often in a cunning or sly way, especially in outsmarting others. Rarely used in a positive sense, usually referring to a formidable, strategic person.. A literal translation of "old" can often sound unnatural to native Japanese speakers if mixed up!
