How to say "Extensive" in Japanese

When translating "extensive" into Japanese, you must choose carefully between 蘊蓄 and 渉猟. In Japanese, 蘊蓄 (うんちく (unchiku)) is typically associated with "extensive knowledge, profound learning, erudition" (Syllabus Level: N1) and represents Refers to deep and extensive knowledge accumulated over time, often implying a detailed understanding of a specific field. Can be used admiringly.. On the other hand, 渉猟 (しょうりょう (shōryō)) maps to "extensive reading, hunting around for information" (Syllabus Level: N1) and represents Refers to reading widely across various materials or fields, often for the purpose of research, study, or gathering knowledge. Suggests thoroughness.. A literal translation of "extensive" can often sound unnatural to native Japanese speakers if mixed up!
