Start with the word after mad. Mad at someone or mad about a problem usually points to anger. Mad about or mad on an activity or person can point to strong enthusiasm, especially in British English. A mad idea often means a foolish or extreme idea. The surrounding words do more work than mad by itself.
Let the context choose the meaning
Do not decide the meaning of mad from one word alone. Look at the noun or phrase that follows it. A person may be mad at a colleague, mad about a delayed train, or mad about a favorite sport. The reason or object usually tells you which meaning fits.
Sam was mad at his roommate for leaving the window open.
The roommate's action caused a problem, so mad means angry.

Photography is an interest, so mad about means very enthusiastic.
In I am mad about the broken printer, what feeling is most likely?
The speaker is probably angry because the broken printer is a problem.
Use mad for informal anger
Use mad for anger in informal English. Mad at someone is a clear pattern. Mad about or mad over an event can also mean angry, especially when the event was unfair, annoying, or disappointing. In a formal complaint, angry, upset, or dissatisfied may state the feeling more precisely.

Mad at names the person who caused Nora's anger.

Use mad about or mad on for strong enthusiasm
Mad about can mean that someone likes a person, activity, team, or subject very much. Mad on has a similar meaning and is especially familiar in British English. This use is informal and energetic. If you want a neutral phrase, use keen on, really likes, or interested in.

Space is the child's interest, so mad on means very enthusiastic.

Recognize foolish ideas and chaotic activity
Before a noun, mad can describe something foolish, extreme, or uncontrolled. A mad idea is a plan that seems unreasonable. A mad rush, mad scramble, or mad dash describes hurried activity that lacks calm order. These uses criticize the plan or describe the situation; they do not diagnose anyone.
Buying tickets without checking the date was a mad mistake.
The speaker thinks the mistake was foolish and avoidable.
At noon, there was a mad scramble for the last empty tables.
Many people moved quickly at once, so the scene was chaotic.
Does a mad rush describe a calm, planned process?
No. It describes hurried and uncontrolled activity.
Choose respectful language about mental health
Some dictionaries record mad in a non-technical sense connected with mental illness. Many people find that label offensive or stigmatizing, especially when it is used about a real person. Say what you know instead: a mental health condition, distress, confusion, or a specific behavior. Do not use a vague word to make a diagnosis or to dismiss someone.
He seemed distressed after the argument, so I asked whether he wanted support.
Distressed describes an observed state without claiming to know a diagnosis.
The clinic offers support for people with mental health conditions.
This names the subject respectfully and does not turn people into a label.
Why is specific language better than calling a person mad?
It is clearer, more respectful, and avoids making assumptions about the person's health.
Before you go
Remember this
Mad can mean angry, very enthusiastic, foolish, or wild and uncontrolled. Check the phrase around it: mad at a person usually signals anger, while mad about an interest often signals enthusiasm. A mad idea is foolish or extreme, and a mad rush is chaotic activity. Avoid using mad as a label for mental illness; clear, specific language is more respectful and more useful.
