These are words that you will almost certainly use in spoken and written language, or in exams. Therefore, we should use these common words as accurately as possible to avoid losing unnecessary points!
The 4 words "See", "Look", "Watch" and "View" all have the Vietnamese meaning of "xem, nhìn" (see, look), and this is why Vietnamese people often confuse these 4 words. I will share some of my experience to help you avoid confusing these words.
First, you should determine the answers to the following 2 questions:
1. Are you looking intentionally or unintentionally?
2. To what extent are you looking at that object?
"See" is a verb of perception, referring to seeing something because it is unintentionally natural, without effort or decision to see it. Usually when using "see", we want to talk about something we do not intend to observe.
For example: I see a bird on the roof.
"Look" is when we look at something intentionally or for some reason, usually having to turn our eyes in a direction to see.
For example: They looked at the picture and laughed.
"Watch" means to watch, follow, observe, that is, to look at something carefully and attentively, paying attention to its developments, usually because it is moving.
For example: After breakfast we go out and watch the men at work.
"View" is a more formal word and has a meaning similar to look, that is, to look at or observe something carefully, possibly to admire it. View is also used to mean watching movies or television.
For example: If you view a rainbow from above, it appears to be shaped like a donut.
Hopefully, my little experience above will help you in some way to use these 4 words correctly.
