thanks
In French, 'merci' is directly translated to 'thanks' in English. It is used to express gratitude or acknowledgment of something given or done. It is often used in conversations after a person has done a favor or granted a request.
Thank you for your help
This phrase is used to thank someone for their assistance. 'Pour' is a preposition that means 'for' and 'votre aide' means 'your help'. Note that 'votre' changes according to the formality and number of people you're speaking to.
Thank you, I understand now
This sentence is typically used after someone has explained something to you. 'Je comprends' is 'I understand' and 'maintenant' means 'now'. The comma separates 'merci', which is used here as an interjection, from the rest of the sentence.
Thank you for inviting me
In this phrase, 'de m'avoir invité' is an infinitive construct used to express gratitude for an action that has taken place. 'Avior invité' is the past participle of 'inviter' meaning 'to invite' and it is preceded by 'me' (contracted here to 'm'), meaning 'me'.
