The phrase "wast sick of" appears in Shakespeare's play Hamlet as part of the line "I am sick of this false world". The spelling of "wast" here is the archaic second person singular past tense of the verb "be", which is now spelled "were". Meanwhile, "sick" is spelled as it is today. The pronunciation of "wast" can be transcribed as /wɑst/, with the "a" sounding like the "a" in "father" and the "t" being pronounced as a glottal stop or a soft "uh" sound.
