subjunctive mood
Quick Summary
The subjunctive mood in grammar is a verb form used to express suggestions, wishes, uncertainty, or possibilities, rather than stating facts. It's one of three main moods in English, alongside the indicative (for facts) and imperative (for commands).1234
The subjunctive is often seen in formal English and can be tricky because its forms are sometimes identical to the indicative mood. It's most noticeable with the verb "be," where the present subjunctive is always "be" (e.g., "It is necessary that he be ready") and the past subjunctive is always "were" (e.g., "I wish it were so"). While its use has decreased in everyday language, it still appears in set phrases and in sentences following verbs like "suggest," "demand," or "wish".34
