Well, you check memory very briefly, make a quick scan, and it's awfully easy to say to yourself, Ring, Rang, Rung, and very hard to say to yourself, Pare, Park: they come more slowly.
شما حافظه تان را سریع چک می کنید و می بینید که خیلی راحت کلماتی مثل Ring ،Rang ،Rung به ذهن می رسند تا کلماتی مثل bare, fort, park
