One example of the subjunctive verb mood is "wish".
The sentence "I wish I were taller" is an example of the subjunctive verb mood. The use of "were" instead of "was" in this sentence reflects the hypothetical or contrary-to-fact nature of the speaker's wish. In the subjunctive mood, we use the base form of the verb ("be") instead of the past tense form ("was").
