noun
your observation; your viewing
Honorific term used to refer respectfully to someone else's act of looking at or examining something. Often appears in formal written contexts such as letters or reports.

ご覧 is a more common and versatile honorific expression for 'looking' or 'watching', while 貴覧 is a stiffer, more formal noun used primarily in written correspondence.
Compound of 貴 (ki, 'noble; your') and 覧 (ran, 'look; view'). The exact historical derivation is uncertain, but the spelling is conventionally associated with respectful reference to another's observation.
