He iti ake te tawhiti o te mea i te roa arotahi o te whakaata kōpiko (s < f)
I runga i ngā tātaitanga i runga i whakaahua whakaata kōpiko Ka taea te whakatau mēnā he iti ake te tawhiti o te mea (s) i te tawhiti arotahi (f), kāti ngā āhuatanga o ngā atarangi i roto i ngā whakaata kōpiko ko:
– Ko te tikanga o Maya, kāore te hihi mārama e whiti mā roto i te atarangi
– Tū tika, kāore rānei i te huripokitia
– Ka nui ake te rahi o te ahua ina tawhiti te mea i te whakaata kōpiko.
– Ka tawhiti atu te mea i te whakaata piko, ka tawhiti atu hoki te ahua i te whakaata piko.

Hei mārama ki te ahua o tētahi mea i hangaia e te whakaata kōpiko, tirohia te tauira pātai me te kōrero e whai ake nei. I roto i tēnei pātai, e whakaarohia ana kei tētahi tawhiti te mea i te whakaata kōpiko, kātahi ka whakaahuahia te hanganga o te ahua o te mea e te whakaata kōpiko , te tawhiti o te ahua mai i te whakaata kōpiko me te whakanui i te ahua i hangaia e te whakaata kōpiko .

Mehemea he 20 cm te roa o te arotahi o tētahi whakaata kōpiko. Whakaahuahia te hanganga o te ahua, kātahi ka whakatau i te tawhiti o te ahua me te whakanui o te ahua mēnā:
a) he iti ake te tawhiti o te mea i te tawhiti o te pūwāhi arotahi (s < f)
b) kei te pūwāhi arotahi o te whakaata te mea (s = f)
c) kei waenganui i te pūwāhi arotahi me te pokapū piko o te whakaata te mea (f < s < R)
d) kei waenganui o te piko o te whakaata te mea (s = R)
