There is no reason this could't be "She is a logical person" Right??
yes, it could be "she is a logical person" :)
Yes, that is accepted.
No, it is not - 21.09.19
I think for "Logical people" it will be "persone logiche".....The h in logiche is just to reserve the "ke" sound.
I am not sure though, a native speaker can explain!
