The spelling of the word "haddest reference to" is heavily influenced by its historical roots. The pronunciation of the word features the [h] sound at the beginning, followed by the short [æ] vowel sound. The middle syllable contains a voiced dental fricative [ð], followed by the [ə] schwa sound. The final syllable features the [s] sound, followed by the [t] sound and the schwa sound once again. The word haddest reference to is an archaic form of "you had referred to," and is rarely used in modern English.
