poor writing; clumsy composition
Humble self-deprecating term for one's own writing, used in formal or literary contexts. Often appears in letters, prefaces, or academic acknowledgments.
Thank you for reading my poor writing.
Though it is clumsy writing, I would be honored if you would kindly look it over.
Compound of 拙 (せつ, 'clumsy, poor') and 文 (ぶん, 'writing, sentence'). The reading せつぶん follows standard on'yomi.
