Ludwig's WRAP-UP

The phrase "which could be" serves as a versatile tool for expressing possibilities and speculative scenarios, as validated by Ludwig AI. Grammatically sound, it commonly introduces nonrestrictive clauses, adding extra information without being essential to the sentence's core meaning. Its frequency is quite high, especially in contexts such as news and media, scientific writing, and encyclopedic content, reflecting its usefulness in qualified statements. When a more declarative tone is required, alternatives such as "that might be" or "that may be" offer subtle yet effective nuances.
