Different uses and meanings of "Like" / How to use it?

The word "like" has different uses and meanings. It can be a noun, verb, adverb, preposition, conjunction, and quotative. So, here is a clear explanation how to use it. 

As a noun

As a noun like has the following meanings:

As a verb

The verb like means:

"to find pleasant or attractive; enjoy."

It can be followed by an infinitive or a gerund:

These two forms often have the same meaning, but sometimes there is a difference.

• When we use like with an infinitive, it expresses habitual preference, something that the speaker does not necessarily like or enjoy but considers as useful, right or wise ( e.g. I like to see my doctor once a year.)
• When like is used with the gerund form, the construction tends to mean that we are actually doing the action (e.g. I like listening to music.)
