allocation
Pluralallocations (some meanings)
- 1The process or procedure of dividing and assigning resources, especially money, among people or purposes.
The committee spent hours debating the allocation of funds across competing departments.
Resource allocation in the hospital follows strict priority rules during emergencies.
Similardistribution, allotment, apportionment, assignment
Note
Here the word names the act of sharing out, not the share. It is allocate plus -ion, and it reached English through Middle French allocacion from Medieval Latin allocātiō. It takes of for what is divided and to for where it goes. RAIL magazine in 2024 writes of an engine's "allocation to Toton" before its transfer to Crewe, the same pattern used for permits and budgets. The portion itself is the amount received.
- 2The amount or share of resources given or assigned to someone as an allowance or entitlement.
Farmers protested when the government cut their annual water allocation.
Each region's allocation of vaccines depended on the size of its population.
Similarallotment, share, quota, ration, allowance
Note
The result rather than the act: what ends up on one person's side when the dividing-up is done. It usually comes with a possessive and a quantity word, as in his full allocation or their annual water allocation. Allowance and entitlement are close neighbors, but allocation keeps a trace of the process behind it. It suggests an amount someone else decided and assigned.
- 3The process by which an embryonic cell and its clonal descendants become limited to a particular cell type or body region.
Researchers tracked the allocation of cells to the neural tube in early embryos.
Lineage allocation in the embryo determines whether a cell contributes to the heart or the gut.
Note
Developmental biology uses the word for a narrowing of fate. Before allocation, a cell's descendants could still contribute to several tissues or regions. Afterward, the whole clone is confined to one. Because the restriction passes to every offspring, it is studied by marking a single early cell and tracing where its descendants end up. The usual frame is allocation of cells to a lineage, germ layer or region.
