Past participles that have become established as adjectives can, like most English adjectives, be modified by the adverb very : a very driven person; We were very concerned for your safety. Very does not modify past participles that are clearly verbal; for example, The lid was very sealed is not an idiomatic construction, while The lid was very tightly sealed is. Sometimes confusion arises over whether a given past participle is adjectival and thus able to be modified by very without an intervening adverb. However, there is rarely any objection to the use of this intervening adverb, no matter how the past participle is functioning. Such use often occurs in edited writing: We were very much relieved to find the children asleep. They were very greatly excited by the news. I feel very badly cheated.
