an automatic mechanical device on a record player that causes new records to be played without manual intervention
"The old jukebox relied on a special changer to spin through its entire library of vinyl without any human help."
Someone or something who changes things.
"The great changer was known for transforming the landscape of the city over decades."
In plain English: A changer is someone who makes things better for everyone around them.
"The automatic money changer at the airport accepted my old banknotes and gave me fresh ones in local currency."
Usage: A changer refers to someone whose job involves exchanging currency, such as at an airport kiosk, rather than the act of changing itself. Do not confuse this person with a mechanic who alters vehicles; if you need money in another denomination, look for the bank teller or automated machine labeled "currency changer."
Inherited from Middle English chaungere, chaungeour ("moneychanger"); equivalent to change + -er.
