Can I put the adverb "exponentially" after the intransitive main verb "grown" when the auxiliary verb "had" precedes the intransitive main verb "grown"? (auxiliary verb + intransitive main verb + adverb) Here is the example sentence.
The corn had grown exponentially since last year.
Or should the adverb come after the auxiliary verb and before the intransitive main verb?
The corn had exponentially grown since last year.
