Expert writing Tips
Best practice
When using "hence", ensure it directly precedes a noun or a clause, not another adverb like "how".
Common error
Avoid using "hence how" because it combines a causal adverb ("hence") with an interrogative adverb ("how"), creating redundancy and grammatical awkwardness. Instead, choose one or the other to clearly express cause or method.

Ludwig's WRAP-UP
In summary, while the phrase "hence how" appears frequently across various sources including science, news and media, and formal business contexts, Ludwig AI indicates that it is considered grammatically questionable. It attempts to combine a causal connection with an explanation of method but does so in a redundant and awkward way. Therefore, it's best to replace "hence how" with clearer alternatives such as "therefore how" or rephrase your sentence to use "hence" or "how" separately. This will ensure grammatical correctness and avoid potential ambiguity, especially in formal writing.
