Etymology
The term 'iron-on' is a modern English compound adjective and noun, formed in the mid-20th century with the rise of synthetic adhesives and DIY culture. It literally describes an item meant to be applied 'on' a surface using an 'iron'. The logic is transparent and functional: the first element names the tool, and the second element describes the action performed with it. This compound follows a productive English pattern (e.g., 'plug-in', 'slip-on') to create terms for consumer products, directly linking the method of application to the product's identity.
