La conjonction même si n’existe pas!

In this paper, we reject the usual definition of même si (even if) as single conjunction and meaning as 'concessive' one. Même si share similar syntactico-semantic properties with 'conditional', but not 'concessive', (class of) conjunctions. In fact, même si is a conjunctive phrase including the si (if) conditional conjunction and the appropriate conditional-conjunction modifier: même (even). 'Concessive' effect is due to même insertion. Meaning of même si has been refined into two semantic interpretation subcategories according to paraphrastic conditional conjunctive phrases: même à (la) condition [que P] or même dans l'hypothèse [où P].
