Ludwig's WRAP-UP
In summary, the phrase "corroborated with that" seeks to validate claims by associating them with supportive evidence. However, as Ludwig AI points out, standard English prefers "corroborated by that" or a similar rephrasing. While the intention is clear, adhering to established grammatical conventions, such as using alternatives like /s/supported+by+that" target="_blank" rel="nofollow">supported by that or /s/confirmed+by+that" target="_blank" rel="nofollow">confirmed by that, enhances the clarity and credibility of your writing. Using the correct preposition is essential for ensuring the message is accurately and professionally communicated. Ultimately, while the meaning is comprehensible, opting for more accepted phrases will elevate the standard of your writing.
