Tabulate is from Latin tabula ('board, tablet, list') + -ate. The verb sense 'to arrange in tabular form' developed in the 19th century. Important recorded forms include tabula (Latin). Morphologically, the word preserves a built structure whose named elements carry the historical sense into English. The semantic development is already visible in the history: an older concrete or specialized use was extended into the modern meaning rather than replaced by a separate origin. In current use it covers to arrange data in a table or systematic column form. The wider family includes derived forms such as tabulation, tabulator, and tabulated and related words such as table, tabular, and tabula.
