Correct spelling for the English word "wast familiar" is [wɒst fəmˈɪli͡ə], [wɒst fəmˈɪliə], [w_ɒ_s_t f_ə_m_ˈɪ_l_iə] (IPA phonetic alphabet).
The term "wast" is the archaic second person singular past tense form of the verb "be" in the English language. It is derived from the Old English word "wǣre" (pronounced /wæːre/), which meant "you were". This word eventually evolved into "wast" to denote "you were" in Middle English.
On the other hand, "familiar" is derived from the Latin word "familiaris", which means "pertaining to a family servant or household". In Middle English, the word "familiar" was often used to describe someone who was closely associated with or intimate with another person. Over time, the meaning expanded to refer to a person or thing that is well-known or easily recognized.
So, "wast familiar" would be an archaic phrase meaning "you were well-known" or "you were easily recognized".
