IPA: /ɪnˈkjuːnəbl/
KK: /ɪnˈkjuːnəbl/
A book printed before 1501, during the early years of printing with movable type.
The library has a rare collection of incunables from the 15th century.
Incunable is derived from the Latin "incunabula" (meaning swaddling clothes or cradle). The term originally referred to books printed before 1501, symbolizing the early stages or 'cradle' of printing technology.
Think of 'cradle' ('incunabula') to remember that 'incunable' refers to the early stage of printed books.
