Napierian + logarithm
The element 'logarithm' makes it clear this is a type of logarithm, so learners would infer it names a particular kind; however 'Napierian' is a proper-name adjective that does not transparently indicate the crucial property (the base e) to a B1 learner without technical/math background. Because part of the meaning (a specific kind of logarithm) is clear but the defining detail (base e / natural logarithm) is not derivable from the constituents, the item is only partially transparent.
Etymology
Napierian logarithm is named after John Napier, a Scottish mathematician who invented logarithms to turn hard multiplication into easier addition, so people used his name for this kind of log. That's why today Napierian logarithm usually means the 'natural logarithm' or the logarithm with 'base e', which is used a lot in higher math.
