• Synonym一片いっぺんWrittenLiterary word for a thin piece or a tiny amount, as in 「一片の雲」 or 「一片の良心」; its written flavor sets it apart from 「断片」.
• Synonym小片しょうへんWrittenWritten-style word for a small piece; it stresses small size rather than being broken or incomplete.
• SynonymフラグメントNeutralLoanword for a fragment, mostly in technical fields like data or gene fragments; in everyday talk 「断片」 is the natural choice.

• Related薄片はくへんWrittenA thin flake or slice, such as the 「薄片」 of a microscope specimen; it stresses thinness rather than breakage.
• Related剥片はくへんWrittenArchaeology and geology term for a flake peeled off, such as a stone-tool flake; specialist usage, not a general word for fragments.
• Related割れわれNeutralA broken piece or crack, and by extension a figure dropping below a level; a mixed-use word only partly overlapping 「断片」.

• Related端くれはしくれNeutralMostly figurative: an unimportant, minor member of a group or profession, as in 「医者の端くれ」, carrying a self-deprecating tone.

Choose 「破片」 for shards of broken glass or pottery, 「かけら」 for a shred or trace, 「切れ」 for a cut piece like bread, and 「薄片」 for thin flakes. 砕片, 細片, 削片, 剥片 and 小片 are written or technical; フラグメント suits tech contexts; 端くれ usually means a minor person.
