Do the noun "partition" and the verb "to partition" by themselves imply disjointness/non-overlapping?

    The term is probably only used in maths. 'A partition of a set A is a collection of nonempty disjoint subsets of A whose union is A.' [Scribd] Here, partitions are into disjoint subsets, so 'disjoint partition' is redundant (a tautology with in this case no redeeming feature). Commented Jul 2 at 12:52
  • I asked ChatGPT and it says partitions are always disjoint. In math partitions are always disjoint, but are they in other fields too? Commented Jul 2 at 13:42
  • @GaslightDeceiveSubvert When you searched for "disjoint partition" what did you find?

    Are you asking about the usage in mathematics, or have you heard this in other contexts? Questions about math terminology are better asked of mathematicians.
