Físeán belongs to the family of Irish words for vision and supernatural sight, related to fís (vision) which appears in the aisling tradition and in early prophetic texts. In poetry the físeán describes the moment of visionary access — the seeing that goes beyond the physical eye to apprehend the supernatural, the beautiful, or the historically hidden. For poets working in the tradition of visionary verse, físeán signals the claim that poetry's sight is qualitatively different from ordinary observation: it is revelation rather than description. The word connects individual lyric experience to the long tradition of Irish prophetic and visionary literature.

Físeán is the modern Irish word for video or television, but in poetic contexts, it can refer to visual media or digital imagery. Poets may use físeán to explore the impact of technology on perception and memory. It contrasts with traditional oral and written forms, raising questions about authenticity and presence. In contemporary poetry, físeán might symbolize the fragmentation of experience or the saturation of visual culture. It represents the evolution of Irish language into the digital age.
