Similar words

部ぶ分ぶん
部分 means 'part' or 'portion' in general, while 一部分 explicitly means 'one part' or 'a single part', emphasizing a specific segment rather than parts in general.
一いち部ぶ
一部 also means 'one part' or 'a part', but is often used in more formal or abstract contexts (e.g., 一部の人は 'some people'). 一部分 is more concrete and commonly used for physical or tangible divisions.

Etymology

Compound of 一 (いち, 'one') + 部分 (ぶぶん, 'part, portion'). The reading いちぶぶん is a straightforward combination of the readings of its components.
