The spelling of the phrase "hast faith" may seem peculiar, but it is actually a case of using archaic English. "Hast" is an old-fashioned form of the word "have" that was commonly used in Shakespearean times. Similarly, "faith" is spelled in the old-fashioned way, without the "e" at the end. In IPA phonetic transcription, "hast" would be pronounced as /hæst/ and "faith" as /feɪθ/. While not commonly used in modern English, understanding these archaic spellings can provide valuable insight into the evolution of the English language.
The phrase "hast faith" is derived from Old English.
The word "hast" is the second person singular present tense form of the verb "have" in Old English. It is related to the Old High German word "hast" and the Old Norse word "hefir". Over time, "hast" evolved into "have" in modern English, but it is still occasionally used in poetic or archaic contexts.
The word "faith" comes from Old English "fæith" or "feith", which in turn is derived from the Proto-Germanic word "faiþō". This word also gave rise to related terms in other Germanic languages, such as the Old Saxon "fēth", Old High German "fida", and Old Norse "feygð". "Faith" refers to a confident belief or trust in something, especially without proof or evidence.
