Ludwig's WRAP-UP

The phrase "they are therefore" serves as a connector, indicating a logical consequence or result. As Ludwig AI confirms, it is grammatically correct and widely used, particularly in news, media, and scientific writing. The phrase functions to bridge two ideas, showing that one is a direct outcome of the other. When using this phrase, ensure the logical connection is clear to maintain coherence. While alternatives such as "consequently" or "as a result" exist, "they are therefore" maintains a unique function in explicitly presenting a deduction. This is common to most of the reputable sources.
