The spelling of the word "hast claim" follows traditional English spelling rules. The word "hast" is an outdated form of the verb "have," conjugated for the second person singular form, and pronounced /hæst/ [hast]. "Claim," on the other hand, has a long "a" sound pronounced /kleɪm/ [kley-m]. Together, "hast claim" means to have a valid or legitimate right to something. While the spelling may seem archaic, it is important to understand traditional English spelling to properly interpret historical texts.
