Here's why:
* English verbs don't have a dedicated future tense form. We use auxiliary verbs like "will" or "going to" to express the future.
* Participles are verb forms used to create different grammatical structures. They're typically used to form compound verb tenses (e.g., "I am *walking*"), adjectives (e.g., "The *fallen* leaves"), or nouns (e.g., "The *rising* sun").
* While we can create participles for other tenses (present and past), there's no "future participle" form.
Example:
* Present Participle: "walking" (used in the present continuous tense)
* Past Participle: "walked" (used in the past perfect tense)
* Future Tense (using auxiliary verb): "will walk"
So, while English has present and past participles, it doesn't have a separate future participle.
