When working on the POs, we may across with new terms that are shortened because in English that is how they are used. Here is one example:
Definition: The learner’s permit allows and encourages beginning drivers to acquire substantial supervised driving experience. To aid this, most States require the learner’s permit to be held for a minimum period of time, and most require a minimum number of supervised driving hours.
ST: learner’s permit
Translation: permiso de conductor principiante
