Difference between "I have ever gone to Seoul" and "I have gone to Seoul"

Introduction:
Both the sentences "I have ever gone to Seoul" and "I have gone to Seoul" are grammatically correct. However, there is a subtle difference in their meaning. In order to understand the difference, let's break down each sentence and analyze it.

Sentence 1: "I have ever gone to Seoul"
This sentence includes the word "ever," which adds emphasis to the verb "gone." The word "ever" implies that the action of going to Seoul has happened at any point in the past. It suggests that the speaker has had the experience of going to Seoul at least once in their life.

Sentence 2: "I have gone to Seoul"
This sentence states a simple fact that the speaker has gone to Seoul in the past. There is no emphasis on the timing or frequency of the action. It does not provide any information about whether the speaker has gone to Seoul multiple times or only once.

Difference:
The main difference between the two sentences lies in the emphasis placed on the action of going to Seoul. Let's break it down further:

1. Timing: The first sentence with "ever" suggests that the speaker has gone to Seoul at some point in their life, regardless of when it happened. The second sentence does not provide any specific information about the timing.

2. Frequency: The first sentence implies that the speaker has gone to Seoul at least once in their life, but it does not specify if they have gone multiple times. The second sentence does not provide any information about the frequency of visits.

3. Emphasis: The word "ever" in the first sentence adds emphasis to the fact that the speaker has had the experience of going to Seoul. It suggests a sense of accomplishment or significance attached to the action. The second sentence is a simple statement of fact without any particular emphasis.

Conclusion:
Both sentences are grammatically correct, but they convey slightly different meanings. The first sentence with "ever" emphasizes the fact that the speaker has had the experience of going to Seoul at least once in their life. The second sentence is a simple statement indicating that the speaker has gone to Seoul without specifying when or how many times. It is important to choose the sentence that accurately conveys the intended meaning based on the context and the emphasis required.
