Why is it called "Nama" as in namarupam?'

Nama, as in namarupa, the designation of 'feeling, perception, attention, intention & contact', why do they call these 'Nama'? Some clues or points to keep in mind; * intention (cetana) is kamma * six classes of intention are sankhara * sankhara fabricates the conditioned * contact has 6 sense media as cause * feeling, perception and sankhara are 'aggregates', are conjoined & are conjoined with 'consciousness' aggregate * 4 aggregates have objects * 3 aggregates always accompany consciousness * consciousness arises as one thing and ceases as another * same consciousness doesn't go from one life to another * consciousness is said to be inbetween two ends, 'form' on one end and 'name' on the other end * both 'the eye' and 'the form visible by the eye' are included under 'form [rupa]' * consciousness meeting rupa is a meeting of the three, is 'contact' * feeling is born of contact * feeling is requisite for craving * everything comes into being through attention * with consciousness as condition, name-and-form comes to be * with name-and-form as condition, consciousness comes to be * from sankhara as a requisite condition comes consciousness * sankhara has ignorance for cause * rupa isn't always generated as in arupajhana, formless perception attainment
