The subjunctive mood is often considered difficult because it is used to express hypothetical or uncertain situations, rather than straightforward facts. This can make it harder to grasp for speakers of languages that do not use the subjunctive mood, as it requires a nuanced understanding of grammar and context. Additionally, the subjunctive mood often involves irregular verb forms and specific rules for usage, which can further complicate the learning process. Overall, the subjunctive mood is challenging for many learners because it requires a deep understanding of language structure and usage.
