The spelling of the word "hadst law on" may confound some due to its antique language form. The correct pronunciation of "hadst" is /hædst/, with a short "a" and a "d" sound like in "dog." The word "law" is pronounced as /lɔː/, with a long "o" and a silent "w." Lastly, "on" is pronounced /ɒn/, with a short "o" like in "hot." Put together, "hadst law on" is an old phrase that means "you have to let it go" or "already happened."
