Ludwig's WRAP-UP
The phrase "definitely likely" aims to express a high degree of probability, but, as Ludwig AI points out, it's considered grammatically incorrect.

While examples can be found in various sources, including News & Media and Science, it is more advisable to use grammatically sound alternatives such as ""most likely"", ""highly probable"", or ""very likely"" to maintain clarity and credibility in writing.
