Ludwig's WRAP-UP
In summary, while the phrase "at deep" appears frequently, particularly in certain technical contexts like naval architecture and, occasionally, sports commentary, it's generally considered grammatically incorrect in standard English. Ludwig AI underscores this point. More precise and widely accepted alternatives, such as "in deep water" or "at a great depth", are recommended for general usage. While authoritative sources like The New York Times and BBC contain examples, the prevalence of Wiki sources indicates a broader, but not necessarily grammatically endorsed, usage. Therefore, discretion and awareness of the context are crucial when encountering or considering the use of "at deep".
