Similarly, original in the sense of 'not copied' cannot normally be intensified or compared, as in the original manuscript, where it does not refer to a quality and there can be only one original manuscript. On the other hand, if original refers to the quality of the work, meaning 'of a new type', it may be intensified or compared: a more original book. We may compare the two uses with those of the corresponding adverb:
She always writes (1) originally. ['in an original manner'] (2) very originally.
She came from Cleveland (1) originally. ['in the first place'] (2) *very originally.

Have I understood it correctly that it should mean something close to 'We may compare the two uses of original ('not copied' and 'of a new type') with the uses of the corresponding adverb (originally)'.
