Can we conclude from the feminine plural form "calculatoarele" that the Romanian noun for the machine is neuter (sing. computerul), or could this sentence also refer to female persons with the task of computing something manually?
Yes, both calculator (calculatoare) and computer (computere) are neuter. The word "calculatoare" could refer to persons, but it's as unlikely as the English "computers" referring to persons who compute.
May be this is not a right place for my question but it is similar so: is the first comment here is valid for
- palton doua paltoane
- un mar doua mere
- un numar doua numare
etc. All of mentioned above I see in different sentences in lessons.
