IPA: /ˈɪʃər/
KK: /ˈɪʃər/
A person or organization that creates and distributes something, such as documents, securities, or licenses.
The issuer of the bonds announced a new investment opportunity.
Issuer → It is formed from "issue" (from Old French *issir*, meaning to go out or to come forth) and "-er" (meaning a person who). An issuer is a person or entity that comes forth to provide or distribute something, such as securities or documents.
Think of someone who 'comes forth' ('issir') to provide something — that's what an issuer does.
