Do you have any examples? Many words can work in many ways.
Student or Learner
I understand that a same word can be adjective and verb or noun and verb etc.
Can you please educate me how it works with example.
1) Articulate ( is both adjective and verb)
We must articulate ourselves in the effective manner.
You can also explain the same with any example.
An articulate person is able to articulate his/her thoughts clearly.

This is a good example of a noun also being a verb. As was noted, the pronunciation is different. We re-CORD a REC-ord.
In English we also sometimes use nouns as adjective. Like we can say "the car door." "Car" here is a noun acting like an adjective to describe the other noun "door." Sometimes this is called an "attributive noun."
Finally, we are not shy about turning nouns into verbs when there is an obvious meaning. Google, the search engine, becomes "google" the activity of searching online.

I have found some information that may interest you.
1. She saw it in the mirror. (preposition)
2. Please come in. (adverb)
3. We knocked at [on] the door, but there was no one in. (adjective)
4. It's the in thing [fashionable] thing to do. (adjective)
5. He has an in [influence] with the manager. (noun)
The idea for these sentences come from The New Oxford American Dictionary (2001).
P.S. Many people plan to gift (verb) their family members and friends next month. It's Christmas, so Santa Claus will be bearing (bringing) many gifts (noun) for good boys and girls. Some people will receive gift (adjective) cards for, say, $100. They can then go to a store and choose anything that is less than $100.
