"Arriver" is used to indicate the arrival of someone or something at a specific location, while "venir" is used to indicate the act of coming to a specific location. "Arriver" is often used to describe the arrival of a person or thing at a destination, while "venir" is used to describe the action of coming from one place to another. In general, "arriver" is used to describe the end point of a journey, while "venir" is used to describe the beginning of a journey. **

Venir becomes venues in the participe passé because it is an irregular verb in French. The past participle of venir is formed by adding -u for the singular masculine form, -ue for the singular feminine form, -us for the plural masculine form, and -ues for the plural feminine form. Therefore, the past participle of venir is venu for the singular masculine form, venue for the singular feminine form, venus for the plural masculine form, and venues for the plural feminine form. **

The main difference between the use of "ir" and "venir" in Spanish is that "ir" is used to indicate movement towards a location, while "venir" is used to indicate movement towards the speaker's location. For example, "voy al parque" means "I am going to the park," indicating movement away from the speaker, while "vienes a mi casa" means "you are coming to my house," indicating movement towards the speaker. Additionally, "ir" is an irregular verb and its conjugation changes depending on the subject, while "venir" is a regular -ir verb and follows a more predictable conjugation pattern. **

"Venir de faire" is formed by conjugating the verb "venir" in the present tense followed by the preposition "de" and the infinitive of the verb you want to express has just been done. For example, "Je viens de manger" means "I have just eaten." "Être en train de faire" is formed by conjugating the verb "être" in the present tense followed by the preposition "en train de" and the infinitive of the verb you want to express is currently being done. For example, "Je suis en train de manger" means "I am currently eating." **

"Être en train" is used to express that someone is in the process of doing something, while "venir de faire" is used to indicate that someone has just finished doing something. For example, "Je suis en train de manger" means "I am in the process of eating," while "Je viens de manger" means "I have just eaten." Both expressions are used to talk about actions in progress or recently completed, but they convey different time frames. **

The verbs venir, boire, and prendre do not typically trigger the use of the subjunctive mood in French. However, they can be followed by the subjunctive in certain situations, such as when expressing doubt, uncertainty, or desire. In these cases, the subjunctive is used to convey a sense of subjectivity or unreality in the sentence. **

The conjugations for the Spanish verb "ir" (to go) are: - Yo voy (I go) - Tú vas (you go) - Él/ella/usted va (he/she/you go) - Nosotros/nosotras vamos (we go) - Vosotros/vosotras vais (you all go) - Ellos/ellas/ustedes van (they/you all go) The conjugations for the Spanish verb "venir" (to come) are: - Yo vengo (I come) - Tú vienes (you come) - Él/ella/usted viene (he/she/you come) - Nosotros/nosotras venimos (we come) - Vosotros/vosotras venís (you all come) - Ellos/ellas/ustedes vienen (they/you all come) **

One would say "dieser Schlüssel" in German. The word "Schlüssel" is a masculine noun, so it takes the masculine form of the demonstrative pronoun "dieser." Therefore, the correct way to say "this key" in German is "dieser Schlüssel." **
