A partial magmatic bialgebra, or $(T; S)$-magmatic bialgebra, where $T ⊂ S$ are subsets of $\mathbb{N} _{\geq 2}$, is a vector space endowed with an $n$-ary operation for each $n ∈ S$ and an $m$-ary co-operation for each $m ∈ T$ satisfying some compatibility and unitary relations. We prove an analogue of the Poincaré-Birkhoff-Witt theorem for these partial magmatic bialgebras.
