What does deposit mean?
Deposit is a versatile English word with two main parts of speech. As a noun, it most commonly denotes a sum of money placed into a bank account, or a partial payment made to secure a purchase — such as a holding deposit on rented accommodation — which may be refundable once conditions are met. It also names any layer of matter laid down by natural forces, as when rivers leave rich sedimentary deposits along their banks. As a verb, to deposit means simply to put or set something down, most frequently to place money into an account for safekeeping. Derived from the Latin deponere, meaning 'to put aside' or 'to lay down', the word carries a neutral to positive connotation: deposits suggest trust, commitment, and gradual accumulation. Its flexibility makes it essential vocabulary in finance, law, property, and earth sciences alike, appearing everywhere from bank statements to geological surveys.
A sum of money paid into a bank account; a partial payment made as security for a purchase or rental; a natural layer of accumulated matter.
"He made a substantial deposit into his savings account."
In legal and financial registers, 'deposit' often implies that the funds are held on trust or as security.
To place something somewhere, especially to put money into an account.

In everyday British speech, people more commonly say 'pay in' a cheque than 'deposit' it.
Regular plural. Commonly used in financial statements ('cash deposits') and geological writing ('alluvial deposits').
"The river's annual floods leave fertile mineral deposits across the valley."
Every bank deposit you make is literally a 'putting down' — from Latin deponere, 'to lay aside'. Your savings have been lying down all along.

Etymology of deposit
Deposit comes from the Latin deponere, formed from the prefix de- ('down, away') and ponere ('to put, place'), originally meaning 'to lay down' or 'to set aside'. The word entered English in the early 17th century, initially in legal and commercial senses relating to money or goods entrusted for safekeeping. It shares its Latin root with cognates such as position, positive, compose, and expose, all built on the same base ponere. Over time its use broadened from purely financial contexts to encompass natural accumulations of matter studied in geology.
