The term "tbill" is a shortened form of the phrase "Treasury bill," which refers to a type of short-term debt issued by the US government. The spelling of "tbill" follows English spelling conventions, with the letter "t" representing the beginning of the word "Treasury" and the word "bill" spelled as it normally would.

A T-bill, short for Treasury bill, is a debt security issued by the United States federal government with a maturity of less than one year. It is considered one of the safest investments in the world due to its backing by the full faith and credit of the U.S. government. T-bills are issued by the Department of the Treasury to finance the national debt, as well as to fund government operations and various programs.
These instruments are sold at a discount to face value and do not typically pay periodic interest like traditional bonds or notes. Instead, investors earn interest by buying the T-bills at a discounted price and receiving the full face value upon maturity. The difference between the purchase price and the face value represents the interest earned.
T-bills are highly liquid investments and are actively traded in the secondary market. They are considered a benchmark for short-term interest rates and are often used as a risk-free reference rate in financial markets. The U.S. government sets the interest rate for T-bills through a competitive bidding process at regular auctions. The yield on T-bills is typically lower compared to longer-term Treasury securities, reflecting their short duration and reduced risk. Investors, including individuals, institutional investors, and foreign governments, often purchase T-bills as a conservative investment option or as temporary parking for excess cash.
The word "tbill" is a colloquial shortened form of the term "Treasury bill".

Thus, "tbill" came into common usage as an abbreviation for Treasury bill among investors, economists, and finance professionals.
