Which one is correct?
- This week is the final week of my staying in this city.
- This week is the last week of my staying in this city.
The words Final and Last are synonyms. They can be used interchangeably most of the time. But it doesn’t mean that both of these words imply the same meaning in all contexts. The context plays a vital role on whether to use Final or Last in a sentence. The word ‘Final’ implies the only being remaining or ultimate. So, “the final week of staying in this city” suggests that there will be no more weeks for staying in this city or it is the only being remaining week for staying in this city. On the other hand, the word “Last” means coming at the end of a series. “The last week for staying in this city” simply means that this week is the last week of all other previous weeks for staying in this city.
Furthermore, the word ‘Final’ is more formal than ‘Last’. To cut the long story short, Final means ‘Last’ according to http://dictionary.cambridge.org/dictionary/english/final ,
Therefore, the former statement implies the letter statement without having much difference between them.
