A relationship existing by virtue of section 39 may be referred to as an adoptive relationship, and—
(a)a male adopter may be referred to as the adoptive father;
(b)a female adopter may be referred to as the adoptive mother;
(c)any other relative of any degree under an adoptive relationship may be referred to as an adoptive relative of that degree,
but this section does not prevent the term " parent", or any other term not qualified by the word " adoptive " being treated as including an adoptive relative.
