How to say "Development" in Japanese

When translating "development" into Japanese, you must choose carefully between 発達 and 展開. In Japanese, 発達 (はったつ (hattatsu)) is typically associated with "development, growth" (Syllabus Level: N4) and represents Refers to the development or growth of something, often abstract like technology, economy, society, or an individual's abilities. Can be used as a noun or as a する-verb. On the other hand, 展開 (てんかい (tenkai)) maps to "development, evolution, expansion, unfolding, progress" (Syllabus Level: N3) and represents Refers to the unfolding or progression of events, a story, a situation, or a business. It can also mean to spread out or expand something.. A literal translation of "development" can often sound unnatural to native Japanese speakers if mixed up!
