The term 'ในที่สุด (nai thîi sùt)' is commonly used in Thai language to denote that something has come to completion, or to indicate the final result or resolution of a storyline or sequence of events. It is generally used at the beginning of the sentence, followed by the result or outcome. It can be used negatively or positively and is equivalent to the English expression 'finally' or 'in the end'.
