Follow-up to daisy#757, which said of these: "Left alone: the negative set relations (∉ ⊄ ⊅) and the subset family (⊂ ⊃ ⊆ ⊇). The source gives 部分集合オブ for ⊂ but nothing for the superset or the negated forms, and I did not want to change half a family." This does the whole family at once.

The defect is the one daisy#757 fixed for < ≤ ≠ ∈: a relation has to work between its operands. A bare noun, or a predicate that ends the sentence, cannot — the second operand follows it and is left stranded.

symbol before reads as after
⊂ A は 部分集合 B "A is a subset" … B A は 部分集合オブ B
⊃ A は 上位集合 B "A is a superset" … B A は 上位集合オブ B
⊄ A は 部分集合でない B "A is not a subset." … B A は ノット 部分集合オブ B
⊅ A は 上位集合でない B "A is not a superset." … B A は ノット 上位集合オブ B
⊆ A は 部分集合または等しい B "A is a subset or is equal." … B A は 部分集合オブ オア イコール B
⊇ A は 上位集合または等しい B "A is a superset or is equal." … B A は 上位集合オブ オア イコール B
∉ x は 要素ではない A "x is not an element." … A x は ノット 要素オブ A
∈/∊, Member x 元 A "x element A" x 元オブ A
∈/∊, In (outside a set) x に含まれる A binds に to x, reversing it x イン A

Where the source has a reading I used it: 部分集合オブ for ⊂, and 部分集合(オブ)・オア・イコール for ⊆, whose オア イコール is the one this translation already uses for ≤ (the ・ marks a word break and is not read). The source gives no superset reading, so ⊃ ⊇ keep the 上位集合 the seed chose and only gain the オブ that lets a set follow them. It gives no negated forms either; ≠ is ノット・イコール there, so the negation is that same borrowed ノット in front of whatever the positive form says, which also keeps ⊄ next to ⊂ instead of inventing a second pattern.

definitions.yaml carries the same readings for intent, so the eight entries of this family are swept with the rules (subset, superset, subset-or-equal, superset-or-equal, not-subset, not-superset, member-of, not-member-of).

Left alone on purpose: the ClearSpeak Belongs option (に属する / 属する / 属さない). Its Japanese is a verb phrase, so fixing it is not a matter of adding the borrowed オブ — it needs a noun the source does not give, and I would be inventing terminology. It stays t: in both polarities and is the one branch of ∈/∊/∉ this PR does not touch.

Checks. audit-translations ja: untranslated text 3447 → 3426, which is exactly the 21 lines promoted from t: to T:; rule differences 30 → 30; missing, extra and definition counts unchanged at 0. Baseline measured on upstream/ja at the same time, not from memory.

Tests. Three new tests (not_element_of, member_and_in_options_work_between_the_operands, subset_and_superset) placed next to the existing membership tests, plus set_non_membership, which pinned the old bare 元でない and now pins the new wording. The subset test uses x and y rather than A and B so that it pins the relation and not the letter names.

Summary by CodeRabbit

  • Enhancements

    • Updated Japanese speech output for set membership, non-membership, subset, and superset symbols.
    • Improved ClearSpeak alternatives for “member” and “in” expressions.
    • Standardized Japanese wording for negated set relationships.
  • Tests

    • Added coverage for membership, non-membership, subset, and superset notation.
    • Updated expected output for Japanese ClearSpeak non-membership speech.

daisy#757 left the negated membership and the subset family alone: the source gives
部分集合オブ for ⊂ but nothing for the superset or the negated forms, and I did
not want to change half a family. This does the whole family at once.

- ⊂ said 部分集合 and ⊆ said 部分集合または等しい. A bare noun, or a predicate
  that ends the sentence, strands the set that follows it: "A は 部分集合 B"
  reads as "A is a subset" and then a B. The source gives 部分集合オブ for ⊂ and
  部分集合(オブ)・オア・イコール for ⊆, where the オア イコール is the one this
  translation already uses for ≤ (the ・ is only a word separator, not read).
- ⊃ and ⊇ keep the 上位集合 the seed chose, since the source gives no superset
  reading, and take the same オブ so they work in the same position.
- ∉ ⊄ ⊅ ended in ではない / でない, which closes the sentence in front of the set
  the statement is about. The source gives ノット・イコール for ≠, so the negation
  is that same ノット in front of whatever the positive form says.
- The ClearSpeak Member option said 元 on its own -- the same missing-preposition
  shape 要素の had in daisy#757 -- and outside a set the In option said に含まれる,
  whose に attaches to what comes before it and so reverses the relation.
- definitions.yaml carries the same readings for intent, so the eight entries of
  this family are swept with it.

Left alone: the Belongs option (に属する / 属する / 属さない). Its Japanese is a
verb phrase, so making it work between the operands is not a matter of adding
the borrowed オブ; it needs a noun the source does not give. It stays t: in both
polarities, and is the one branch of ∈/∊/∉ this commit does not promote.

The new Japanese non-membership test has an incorrect comma in its expected output, which can block the test suite; the localized assertion fix should be made before merging.

Remove the comma from this ClearSpeak expectation.

The ∉ ClearSpeak Element branch emits ノット 要素オブ without punctuation. The shared helper selects that branch with ClearSpeak_SetMemberSymbol = "Element", so the expected output should be x ノット 要素オブ 大文字 エー.

Proposed fix
-        "x ノット 要素オブ, 大文字 エー")?;
+        "x ノット 要素オブ 大文字 エー")?;
