To replace something means to put something else in its place.
When something gets old and begins to break down, it may need to be replaced.
(The person who replaces someone is the person's replacement.)
To tear something down means to break it apart.
To tear a person down means to hurt them by saying negative things about them.
(When the old school building was torn down, it was replaced by a hotel.)
To construct something means to build it, or put it together.
Large construction projects include buildings, bridges, and organizations.
The opposite of constructive, is destructive.
(The earthquake destroyed several buildings and left many people without homes.)
To organize something means to arrange things in an orderly, logical way.
An organization is something that has a logical structure, such as a well-managed company.
To support something such as an idea is to help or add strength to it.
The opposite of support is to undermine or weaken.
Some people are poorly organized, so they have a hard time finding things.
It may take a long time to tear down a big building.
If you support someone，it means you are trying to help them succeed.
