When you determine something, you conclude or ascertain it by reasoning or observation. When you verify something, you prove its truth or correctness, or you confirm it. There is a resoluteness to both terms, but verify has veritas (truth) at its core. To verify the accuracy of information, as a journalist does, is to fact-check it or confirm that it’s true. To verify the authenticity of an antique or artwork is to confirm its provenance or history of ownership. And to verify the identity of someone, as when accessing sensitive information online, is to make certain that that person is who they claim to be.

The adjective innovative emphasizes the introduction of something new. It is similar to the adjective creative insofar as it deals with originality, but innovative is far less likely to describe artistic endeavors, such as painting or writing. It is more at home in the world of technology and business-oriented problem solving, likely influenced by commercially oriented uses of the noun innovation to refer to new products introduced on the market, or the act of introducing new products.

The verbs start and launch are both used to talk about setting something into motion, but launch implies movement of a bolder or more sudden nature. Material objects that are launched (rockets, missiles) are sent out with some force. This sense of blasting or bursting forth is carried over into the launching of things immaterial, such as campaigns, initiatives, or careers. Additionally, a person who launches into speech or action plunges right in, again suggesting a boldness or forcefulness that would be lost if they were to start to speak instead.
