dyma'r dull a argymhellir gyda golwg ar derminoleg hefyd lle bo modd.
this is also the recommended approach whenever appropriate.

nid yw hyn yn golygu nad yw'n ddull dilys lle caiff ei ddefnyddio, ond nad yw'n ddull a argymhellir.
that isn’t to say that it isn’t a valid approach where it is used, but that it isn’t a recommended approach.
