quasi (adv.)

"as if, as it were," used in introducing a proposed or possible explanation, late 15c., a Latin word used in Latin in hypothetical comparisons, "as if, just as if, as though;" in real comparisons "just as, as;" and in approximation, "somewhat like, nearly, not far from." It is from quam "as" relative pronominal adverb of manner (from PIE root *kwo-, stem of relative and interrogative pronouns) + si "if" (from PIE pronominal stem *swo- "so;" see so).
