Quasi, means 'as if'. Seemingly but not actually; in some sense; resembling; nearly, Black's Law Dictionary, 7th Edn., p. 1257.
Means a Latin word frequently used in the civil law, and often prefixed to English words. It is not a very definite word. It marks the resemblance, and supposes a little difference, between two object, and in legal phraseology the term is used to indicate that one subject resembles another, with which it is compared, in certain characteristics, but that there are also intrinsic and material differences between them. It negatives the idea of identity, but implies a strong superficial analogy, and points out that the conceptions are sufficiently similar for one to be classed as the equal of the other, 74 C.J.S. Quasi, at 2 (1951).
This word prefixed to a noun means that although the thing signified by the combination of 'quasi' with the noun does not comply in strictness with the definition of the noun, it shares its qualities, falls philosophically under the same head, and is best marked by its approximation thereto. The titles next following furnish examples.
