The word "Guills" does not have a commonly recognized spelling in standard English. However, it may be pronounced as /ɡɪlz/ or /ɡuːlz/ in certain dialects or accents. The first pronunciation, written with the IPA symbols for voiced velar stop and voiced alveolar fricative, is similar to the word "gills" that refers to the breathing organs of fish. The second pronunciation, written with the IPA symbols for voiced velar stop and oo sound, is also similar to "gules," the term used in heraldry to describe a red color.
