The Greek verb diaireō means to divide, distribute, or apportion — to split something among parties. It appears in Luke 15:12 where the prodigal son demands his share of the inheritance ('divide the estate between us'), and in 1 Corinthians 12:11 where the Spirit 'apportions' gifts to each individually as He wills.
The contrast between the two uses of diaireō is theologically rich. The prodigal's demand for division is an act of rebellion — wanting what is his without the relationship that gives it meaning. He wants the Father's goods without the Father. The Spirit's apportioning of gifts is the opposite: a gracious, sovereign distribution to each member of the body for the common good. The same word — division/distribution — can describe either selfish grasping or gracious giving, rebellion against the Father or the Spirit's generosity flowing from the Father. The prodigal who demanded his share eventually returned to the Father Himself; we receive spiritual gifts not to hoard but to pour out in service.
