誊 is not used alone in modern Chinese; it is bound in 誊写 and 誊清 - copying a draft out into a clean fair copy. It is the speech radical 言 under a contracted top borrowed from 朕, the phonetic that also feeds 腾 and 誊.
register
Bound and somewhat formal; 抄写 is the everyday word for copying out text.
言 is the full speech radical in its bottom-position form. Copying out a document is putting words down again, so the speech element supplies the meaning.
phonetic
龹
contracted phonetic from 朕
This 6-stroke top is a contracted, fused form of the phonetic 朕 (standalone 10 strokes), shared by 腾 and 誊. It supplies the téng sound; the historical pieces have merged so it no longer reads as an independent character.
