What would be the right position of "substantially" in the following:
1). Before verb: These optimal values substantially contribute to the success of the methodology.
2). After verb: These optimal values contribute substantially to the success of the methodology.
Here is my issue:
Fact1: When I use Google Ngram, I get this, 0 occurrence of option 1.
Fact2: I found an excellent Grammar book that discusses Adverbs, their types and prefered positions. The author defines some rules that I'll summarize as follows:
- Connecting adverbs, eg: however, then,..., Position: Beginning of clause.
- Indefinite frequency, eg: always, usually,..., Position: Mid position (after auxilary verb, before other verbs) sometimes beginning of clause.
- Focusing adverbs, eg: mainly, only,..., Position: Mid position.
- Adverb of certainty, eg: clearly, obviously, Position: Mid position.
- Adverb of completeness, eg: almost, nearly,..., Position: Mid position.
- Adverb of manner, eg: fast, slowly, nicely,..., Position: End clause, mid and beginning.
- Adverb of place, eg: upstairs, around, Position: End clause, sometimes beginning.
- Adverb of time, eg: daily, weekly, ... Position: Mostly end clause, sometimes beginning and mid position.
I think that "substantially" is an adverb of completeness. Therefore, the right position is before the verb "contribute" (option 1). However, Google Ngam indicates that option 1 is not widely used.
What do you think? Any suggestions?
