TRASPOLACIONES word non-existent . It is intended, by the one who pronounces or writes it, usually journalists, to imply the application of conclusions obtained in a given field, to another similar one. But this logical operation has the name extrapolaTION and its corresponding verb is EXTRAPOLATE . On the other hand, transpolar is an adjective and not a verb, whose meaning is 'passing through the pole or its vicinity', as in "transpolar flight" or "transpolar flight". It is worth clarifying that the most learned form of the prefix is almost always trans, but due to the great frequency of its use or misuse when said after instead of trans, the RAE has accepted, for example, 'transmit' for transmitting and 'traspirar' for transpiring. There are cases when the correct, and only, way is after, as in trespassing or disrupting.
