Nする vs Nをする (separable する compounds)
grammar9 sentences
The distinction between fused suru-compounds (勉強する) and the separated form with を (勉強をする). Many Sino-Japanese nouns can verbalize either way; both are correct. The bare form is more compact and verb-like; the を form treats the noun as a separable object — useful when modifying it (親切な世話をする works, *親切な世話する does not), or when an adjective or quantity is added.
