The subjunctive mood expresses wishes, suggestions, demands, or hypothetical situations—things that aren't real or certain.

Why It Matters

In most English, we use regular verb forms. But in certain formal situations, the subjunctive uses a special form:

Regular: He is late. Subjunctive: I suggest that he be on time. (not "is")

Regular: She goes to school. Subjunctive: I demand that she go immediately. (not "goes")

Notice: No -s on the verb, even with he/she/it.

When to Use It

1. After verbs of suggestion, demand, or request:

• suggest, recommend, propose
• demand, insist, require
• request, ask

Pattern: I suggest/demand that + subject + base verb

Examples:

• I suggest that he be here at 9.
• She demands that they arrive on time.
• We recommend that she study more.

2. After "It is + adjective" (importance/necessity):

• It is important/necessary/essential/vital/crucial

Examples:

• It is important that he be present.
• It is essential that she finish today.
• It is necessary that we leave now.

3. Wishes and hypotheticals with "were":

Use "were" for all subjects (not "was"):

• I wish I were rich. (not "was")
• If I were you, I would study more.
• She acts as if she were the boss.

Examples by Level

• B1: I suggest that he study harder.
• B1: It is important that she be on time.
• B2: The doctor recommended that I take the medication daily.
• B2: If I were in your position, I would accept the offer.

Common Mistakes

❌ I suggest that he is here at 9. ✅ I suggest that he be here at 9.

❌ It's important that she goes today. ✅ It's important that she go today.

❌ I wish I was rich. ✅ I wish I were rich. (formal)
