✨ Lesson 5: The Subjunctive Mood
Today, we are learning about a special verb form called the Subjunctive Mood1. The subjunctive is not used for facts; it's used to talk about things that are not real, such as a demand2, a recommendation3, a hypothesis4, or a wish. It is most common in formal English, especially in writing.
The Present Subjunctive: The "Base Form" Rule
The present subjunctive is formed using the base form5 of the verb (the infinitive without 'to'). The most important rule is that this verb form never changes, even for subjects like 'he', 'she', or 'it'. This structure is triggered by certain verbs and adjective phrases.
Structure: Trigger Word + that + Subject + Base Form Verb
Common Trigger Verbs: suggest, recommend, demand, insist, request, propose.
- "The manager insists that every employee be on time." (not 'is')
- "I recommend that he apply for the job." (not 'applies')
Common Trigger Adjectives: It is vital, essential, important, necessary, crucial.
- "It is essential that she attend the meeting tomorrow." (not 'attends')
- "It is necessary that a valid passport be shown at the border." (passive form)
The Past Subjunctive (A Quick Review)
You have already been using the past subjunctive without knowing its name! It is used in unreal conditionals and wishes to talk about the present. The most common example is using 'were' instead of 'was'.
Second Conditional: "If I were you, I would take the job."
Wishes: "I wish I were on holiday right now."
