The etymology of いわゆる is straightforward. It is a combination of the verb 言う (iu: to say, to call) and the adverbial particle は (wa), the verb ending れる (reru: passive/potential verb ending), implying something that is "spoken of" or "called." The final "u" is dropped to make it sound better. The "yo" sound in いわゆる is the result of the sound changes that take place when a particle is attached.
