While the term watch it will always imply and refer the extreme attention of an individual on any issue, according to the context in which it is used, it may refer to various issues or situations.
For example, in a medical context, when a medical professional in a certain specialty is dedicated to the task of carefully examine the evolution of the disease or condition that a patient presents, in common language this activity that the doctor performs is called observing.
On the other hand When you want to realize that a rule or order issued by an authority must be complied with, yes or yes, the term observe is often used.. For example, in the rules of a company it is established that the personnel must arrive early at a fixed time, while an employee one, two, three and up to four times incurs late arrivals, then, his boss or immediate superior will ask him Please observe the rules regarding attendance and tardies.
Too, when something or someone looks at each other with great attention and care for some questionEither because of the desire they provoke or because the mission of following up on that person or thing is being fulfilled, the term observing is often used to describe such activity.
Likewise, when on the other hand the intention is to tell the other that we have noticed something different or different in their actions or physical appearance The following expression is usually used: I have observed that you are skinnier or, I observe that you have cut your hair.
From everything we mentioned above, it follows that to observe is to see something or someone, but it also supposes a broader activity than the simple fact of seeing or contemplating something, because observing is something like the initial and first step of any process or mental activity. That is, if I am studying any question, the activity of observing will be a fundamental fact when it comes to understanding and keeping that knowledge in my mind, because observing, observation, is a fundamental step when it comes to knowing and within the learning process.
