Interspersed

Interspersed is the past participle of the verb intersperse, meaning to scatter or place things at intervals among other things. As an adjective, interspersed describes elements that are distributed at intervals within a larger sequence or space, rather than being contiguous or uniform throughout. The term implies both grouping and variety, as items appear in between other items.

Etymology: The word is derived from the verb intersperse, itself formed from the Latin elements inter- meaning between and spargere meaning to scatter. The noun form interspersion denotes the act or result of interspersing.

Usage: In literature and writing, sentences may be interspersed with anecdotes, quotations, or clarifications, producing a texture of alternating elements. In design and layout, sections or color blocks can be interspersed to create rhythm. In biology and genomics, interspersed repeats refer to repetitive DNA sequences that are dispersed throughout the genome, such as LINEs and SINEs, in contrast to tandem repeats that occur in adjacent copies. The phrase interspersed with is commonly used to indicate that one thing is mixed among others.
