📖 Theory 1 of 3 · What Is the Subjunctive?

The Subjunctive Mood

In English, verbs have moods. The indicative mood states facts. The subjunctive mood is used in formal writing to express things that are hypothetical, wished for, demanded or recommended — things that may not be (or are not yet) real.
🔵 Indicative
States facts or describes what is true right now.

"He is present."
"She attends every meeting."
📜 Subjunctive
Expresses wishes, hypotheticals or formal demands.

"It is vital that he be present."
"I suggest that she attend every meeting."
⚠️ Notice: In the subjunctive, the verb does not follow the usual rules. For third-person singular, there is no –s ending: we write "he be" not "he is", and "she attend" not "she attends".

📖 Theory 2 of 3 · The "Were" Subjunctive

Type 1: Hypothetical "Were"

In formal English, we use were for all subjects (I, he, she, it, they) when describing a hypothetical or contrary-to-fact situation — something that is not (or not yet) real.
🟠 Pattern
If + subject + were + [to + verb / adjective / noun] , [main clause]
or: Were + subject + [to + verb] , [main clause]  ← very formal
SubjunctiveIf I were you, I would apologise immediately.
SubjunctiveIf she were to apply, she would certainly succeed.
SubjunctiveIf it were possible, we would help at once.
Very formalWere I to disagree, I would say so formally.
Informal/spokenIf I was you… (acceptable in speech, not in formal writing)
⚠️ Key rule: In formal writing, use were for all subjects in hypothetical "if" clauses — even when you might say "was" in casual speech. "If I were…" not "If I was…"
📖 Theory 3 of 3 · The "That-Clause" Subjunctive

Type 2: Demands, Recommendations & Formal Necessity

After certain verbs and phrases expressing demands, suggestions or importance, we use a "that" clause where the verb stays in its base form — with no –s, no –ed, no –ing — regardless of the subject.
🔵 Pattern
[Trigger verb/phrase] + that + subject + [base-form verb]
Common trigger verbs:
suggestrecommenddemandinsistrequirerequestproposeaskorder
Common trigger phrases:
It is vital that…It is essential that…It is important that…It is necessary that…It is imperative that…
