Ludwig's WRAP-UP
The phrase "I sustaining" is grammatically incorrect and rarely used in standard English. As Ludwig AI points out, it requires an auxiliary verb to form a coherent sentence. Instead, consider using phrases like "I am sustaining", "I have sustained", or "I continue to sustain" to convey your intended meaning accurately. While the search results show examples in news and scientific contexts, the fundamental grammatical error limits its acceptability. Pay close attention to including necessary auxiliary verbs to avoid this common mistake.
