Subjunctive Mood
The safest approach is to identify the construction rather than labeling every hypothetical past form as subjunctive. Mandative base-form clauses and irrealis “were” are clear practical patterns, while other counterfactual forms may be analyzed differently.
English subjunctive patterns appear in contexts such as demands or recommendations (“They insisted that she be present”) and in traditional irrealis “were” (“If I were you”). Grammar frameworks differ in how broadly they apply the label, and modern usage varies by dialect and register.
Key details
Important caveats
Boundary
Do not call every past-tense form in a hypothetical sentence morphologically subjunctive without qualification.
Further guidance
Diagnostic
Look for the construction: a demand/recommendation followed by a base-form clause, or a traditional irrealis “were” pattern, before applying the label.
Variation
Modern English often offers alternative constructions, and dialects differ in how frequently the subjunctive patterns are used.
Worked Example
“The committee recommended that the report be revised” uses a base-form mandative pattern; “If I were responsible, I would revise it” uses traditional irrealis “were.”
