specimenoften
The term "specimenoften" appears to be a portmanteau, a blend of the words "specimen" and "often". A specimen, in its most common usage, refers to an example or sample of something, particularly in scientific contexts like biology, geology, or medicine. An "often" indicates a frequent occurrence. Therefore, "specimenoften" could conceptually refer to a situation where specimens are frequently collected, observed, or encountered.
This term is not a standard scientific or technical term and is likely to be used informally
