Accomptant

Accomptant means exactly the same as accountant; only the spelling has gone out of use, and dictionaries now mark it obsolete. You meet it in older documents, where it names the person who kept or examined someone's money accounts.

By the census era the modern spelling had taken over. From 1910 the instructions told enumerators to report an accountant, bookkeeper or cashier by that exact title and not simply as a clerk, so later returns usually say accountant.
