Meddyg ydw i, ond does ddim geiriadur meddygol CYMRAEG gydaf. Rwy'n byw yn South Carolina (UDA). Ble/sut allaf i brynu un? Na allaf i wahaniaethu rhwng enwau y llythyrau ""i" ac "u". Rwy'n wedi clwyd "i-dot" am enw y lythyr "i". Diolch yn fawr. Dr. Glyn Thomas Gowing. English translation because my Welsh most likely has everyone confused by now (because it's so bad): I'm a doctor, but I don't have a Welsh-language medical dictionary. I live in South Carolina (USA). Where/how can i buy one? How does one answer a command? "Come here!" "???" I cannot differentiate between the names of the letters "i" and "u". I have heard "i-dot" for a name of the letter "i". is that acceptable? Thank you very much. Dr. Glyn Thomas Gowing
