"Will + participle 2" is a construction used to form the future perfect tense in English. It is used to indicate an action that will be completed before a specific point in the future. This construction is formed by using the auxiliary verb "will" followed by the past participle of the main verb. For example, "By the time you arrive, I will have finished my homework." **

The Latin present participle is formed by adding -ns, -ntis to the present stem of the verb. For example, the present participle of the verb "amo" (I love) is "amans, amantis" (loving). The perfect passive participle is formed by adding -us, -a, -um to the verb stem. For example, the perfect passive participle of the verb "amo" is "amatus, amata, amatum" (loved). The future active participle is formed by adding -urus, -ura, -urum to the verb stem. For example, the future active participle of the verb "amo" is "amaturus, amatura, amaturum" (about to love). **

A participle is a form of a verb that can function as an adjective or be part of a verb phrase. There are two types of participles in English: the present participle, which ends in -ing (e.g. "walking"), and the past participle, which can end in -ed, -en, -d, -t, -n, or -ne (e.g. "broken"). Participles are used to modify nouns or pronouns, and they can also be used to form verb tenses such as the present perfect or past perfect. **

Participle clauses are a type of clause that uses a present participle (-ing form) or a past participle (-ed form) to provide additional information about the subject of the main clause. They can be used to show simultaneous actions, cause and effect, or to provide descriptive details. For example, in the sentence "Feeling tired, she decided to go to bed," the participle clause "Feeling tired" provides additional information about the subject "she." **

The past participle is a verb form used to indicate a completed action or state that occurred in the past. It is often used with auxiliary verbs to form the perfect tenses (e.g., "has eaten," "had gone"). The present participle, on the other hand, is a verb form used to indicate an ongoing action or state in the present or future. It is formed by adding "-ing" to the base form of the verb and is used to create the progressive tenses (e.g., "is eating," "will be going"). **

The terms premature, simultaneous, and subsequent can be explained in relation to past participle, present participle, and future participle based on their timing in relation to the action of the verb. The past participle refers to an action that has already been completed, making it premature in relation to the present moment. The present participle refers to an action that is happening at the same time as something else, making it simultaneous. The future participle refers to an action that will happen at a later time, making it subsequent to the present moment. These terms help to clarify the timing of the action in relation to the verb. **

A substantivized participle is a verb form that has been turned into a noun by adding a definite article and declining it for case, gender, and number. In other words, it is a participle that has been transformed into a noun and can function as a subject, object, or complement in a sentence. This process allows the participle to take on the characteristics of a noun while still retaining some of its verbal qualities. **

A nominalized participle is a verb form that has been turned into a noun. This is done by adding a suffix to the participle form of the verb, which allows it to function as a noun in a sentence. Nominalized participles are commonly used in various languages to express actions or qualities in a more abstract or general way. **
