Ludwig's WRAP-UP
In summary, "directly contiguous" is a grammatically correct and usable phrase employed to describe entities that are immediately adjacent without any intervening space. Ludwig confirms its validity. While not exceedingly common, the term finds frequent use in scientific, news, and encyclopedia contexts where the precision of spatial relationships is crucial. When choosing the appropriate wording, consider whether the emphasis on immediacy and uninterrupted connection is essential; if not, simpler alternatives like "adjacent" or "next to" may suffice. Steer clear of overusing the phrase in instances where such emphasis is redundant.
