  We study a new type of the modified teleparallel gravity of the form
$F(T,\,\Theta)$ in which $T$, the torsion scalar, is coupled with $\Theta$, the
trace of the stress-energy tensor. In a perturbational approach, we study the
stability of the solutions and as a special case we find a condition for
stability of the de Sitter phase. Then we adopt a suitable form for
$F(T,\Theta)$ that realizes a stable de Sitter solution so that the stability
condition creates a specific constraint on the parametric space of the model.
Finally, the energy conditions in the framework of $F(T,\Theta)$ gravity is
investigated.
