A
phonogram is a
grapheme (written character) which represents a
phoneme (speech sound) or combination of phonemes, such as the letters of the
Latin alphabet or the Japanese
kana. For example, "igh" is an English-language phonogram that represents the hard "I" sound in "high". Whereas the word
phonemes refers to the sounds, the word
phonogram refers to the letter(s) that represent that sound.
