Bonjour
<em>Does </em><em>m'</em><em> acts as a reflexive pronoun ?</em>
<em />
YES. it does !!
EXPLANATION
me, m' = me, myself
te, t' = you, yourself (informal you)
se, s' = him(self), her(self), it(self)
nous = us, ourselves
vous = you, yourselves <em>(formal you & plural you)</em>
se, s' = them(selves)
when the following word begins with a vowel, for a nicer sound, there is an elision with me, te, se = m', t', s'
