Translation guide
The English adverb 'partially' means 'not completely' or 'to some extent'. In Japanese, it is expressed through adverbs, adverbial phrases, or sentence patterns that indicate partialness. The most common and versatile equivalent is 一部 (ichibu) meaning 'a part' or 'partially'. Other options include 部分的に (bubunteki ni) for 'partially' in a more formal or technical sense, and patterns like ～だけ (dake) or ～しか～ない (shika~nai) to express limitation. The choice depends on whether you are emphasizing that something is incomplete, only a portion, or not entirely the case.

Topic-marked phrase meaning 'part of it' or 'some of it'. Used to state that a portion of something has a certain quality or does something.

English '-ly' adverbs often do not have direct one-word equivalents in Japanese. Using パーシャリー (pāsharī) is not natural. Instead, use the noun 一部 or adverbial phrases like ある程度. Also, be careful not to overuse 部分的に in casual contexts.
