Ludwig's WRAP-UP
The phrase "I suspect if" is a common construction used to express a tentative belief or prediction contingent on a specific condition. However, Ludwig AI identifies this phrase as grammatically incorrect. Despite its frequent appearance in various sources, particularly in news and media, adding "that" after "suspect" (e.g., "I suspect that if") often provides greater clarity and grammatical soundness. When writing, carefully consider your intent and the desired level of formality, and explore alternative phrases like "I believe that if" or "I think that if" to enhance precision and avoid potential ambiguity. Although frequent in certain contexts it's important to use it carefully, aware that you are using an incorrect construction.
