Definition 2.2.10. A unital $\infty$-operad $\mathcal{Q}$ and an object $X\in\underline{\mathcal{Q}}$ determine a pointed unital $\infty$-operad $\mathcal{Q}_{X}\in\mathbf{Op}_{\infty,*}^{\operatorname{\scriptsize{un}}}$. We denote $\operatorname{End}_{\mathcal{Q}}^{\operatorname{\scriptsize{red}}}\left(X\right):=\left(\mathcal{Q}_{X}\right)^{\operatorname{\scriptsize{red}}}$ and call it the reduced endomorphism $\infty$-operad of $X$ in $\mathcal{Q}$.
