Two words somehow became issues of debate during our last meeting:
(1) Pen drive
(2) Monograph
As to (1) even though it is among one of the technically correct terms to refer to a USB drive both in Britain and in the US, its level of frequency is close to non-existent. You’ll be on the safe side if you refer to that gadget as a flash drive. The same holds true for (2), which refers to A scholarly piece of writing of essay or book length on a specific, often limited subject. Monographs are dealt differently in the US and in Britain from the way the so-called “monografias” are dealt in Brazilian Colleges and Universities. Nevertheless in the absence of a better term, monograph may be used (to a certain extent) in English in the same context as the word “monografia” in Portuguese.
