What is communication? The process
Communication means sharing information, ideas and feelings so that the other person understands them the way you meant. It is a two-way process with these parts:
- Sender: has an idea and encodes it (chooses words, pictures or gestures).
- Message: what is being shared.
- Channel (medium): face to face, phone call, letter, email, chat, a poster, a video.
- Receiver: decodes the message — turns it back into meaning.
- Feedback: the receiver's response — a nod, a reply, a question. It shows whether the meaning arrived.
- Context: the situation — who, where, when, why — which shapes all the other parts.
Communication can be one-way (a notice board, a radio advert) or two-way (a conversation). Two-way is slower but more accurate, because feedback lets us correct mistakes.
Barriers to communication and how to remove them
- Physical: noise, distance, a weak phone network, bad lighting.
- Language (semantic): jargon, long sentences, a language or accent the listener does not know, words with two meanings.
- Emotional (psychological): anger, fear, sadness, stress, shyness. A person who is upset hears less.
- Cultural: different customs about eye contact, distance, greetings and what is polite.
- Personal: not listening, assuming, interrupting, a closed mind.
Fixes: pick a quiet place and a good time; use simple, clear words; stay calm and wait if emotions are high; learn about the other person's culture; check understanding ("Shall I repeat that?").
In families, strong feelings are normal. Use I-statements — "I feel worried when you come home late, because I don't know you are safe" — instead of blaming "You always…". This shares the feeling without starting a fight.
Verbal, non-verbal and visual communication
Verbal communication uses words. It can be oral (speaking: talks, calls, meetings) or written (letters, emails, reports, messages). Speech is quick and personal, with instant feedback; writing is permanent, can be planned and checked, and can reach many people.
Non-verbal communication is everything except the words:
- Facial expression (smile, frown)
- Eye contact
- Gestures (a thumbs-up, a wave)
- Posture (standing straight, arms crossed)
- Personal space (how close we stand)
- Paralanguage: tone, speed, loudness and pauses of the voice
Visual communication uses pictures, charts, signs and symbols. When words and body language disagree, people usually believe the body language, so keep them matched.
Active listening and the 7 Cs
Hearing is just sound reaching the ear. Listening is paying attention to understand. Active listening means:
- Look at the speaker; put your phone away.
- Let them finish without interrupting.
- Ask open questions to clear doubts ("What happened next?").
- Paraphrase: say it back in your own words ("So the test moved to Monday?").
Empathy means trying to feel what the other person feels. It builds trust in friendships and families. How we see ourselves (self-concept) also matters: a confident person speaks more clearly, and kind, honest communication builds that confidence in others.
The 7 Cs of effective communication
Clear, Concise, Correct, Complete, Concrete (specific facts), Courteous (polite) and Considerate (thinking of the listener).
Context, register and everyday situations
Register is the style of language for a situation. Formal: with a principal, in an interview, in an official email — polite words, full sentences, no slang. Informal: with friends and family — relaxed and friendly.
- Asking for information: "Could you tell me when the library opens?" Giving it: clear, in order, with facts.
- Request: "Could you please…?" / "Would you mind…?"
- Refusal: thank, say no clearly, give a short reason, offer another option: "Thanks for asking. I can't come on Saturday because of practice, but I'm free Sunday."
- Apology: say sorry, name what you did, take responsibility, promise to fix it: "I'm sorry I broke your pen. It was my fault. I'll replace it tomorrow."
- Social contact: greeting, introducing, thanking, saying goodbye — the small talk that starts relationships.
Clear sentences need the right word order and parts of speech: a subject (who), a verb (does what) and the details. In correspondence, an email or letter has a subject line, greeting, short paragraphs, a polite closing and your name.
Assertive and professional communication
Three styles:
- Passive: hiding your needs ("It's fine…" when it isn't).
- Aggressive: pushing your needs and ignoring others (shouting, blaming).
- Assertive: stating your needs honestly and calmly while respecting others. This is the healthy goal.
At work and in projects, communication must also be ethical: honest, respectful, keeping private information private, and on time. In technical and science communication, explain the aim, method, results and conclusion clearly; use diagrams, tables and correct units; know your audience (a classmate vs an expert); and say what you are not sure about.
Key formulas and definitions
- Process: Sender → encode → Message → Channel → decode → Receiver → Feedback
- Barriers: physical, language, emotional, cultural, personal
- Types: verbal (oral, written), non-verbal, visual
- Active listening (LEAP): Look, let them finish, Ask, Paraphrase
- 7 Cs: clear, concise, correct, complete, concrete, courteous, considerate
- Kind refusal = thanks + clear no + short reason + another option
Worked examples
1. Identify the parts: Riya sends a WhatsApp message to her teacher asking for the homework. The teacher replies with a photo of the page.
Sender: Riya. Message: request for the homework. Channel: WhatsApp (written, digital). Receiver: the teacher. Feedback: the photo reply. Context: informal app but a teacher, so Riya should still be polite.
2. Rewrite this message in a formal register: 'hey sir cant come tmrw sick'.
'Dear Sir, I will not be able to attend school tomorrow, 5 March, because I am unwell. I will catch up on the work I miss. Thank you. Yours sincerely, Arjun Mehta, Class 9B.'
3. Your friend says 'I'm fine' with folded arms, looking at the floor, in a flat voice. What should you do?
The non-verbal signals (closed posture, no eye contact, flat tone) do not match the words. Gently check: 'You seem a bit low. Do you want to talk?' Then listen actively without pushing.
Common mistakes
- Thinking communication is only talking. Listening and feedback are half of it.
- Ignoring body language. If your face says 'bored', your polite words lose their meaning.
- Using the same informal style with everyone. Match the register to the context.
- Confusing assertive with aggressive. Assertive is calm and respectful; aggressive attacks the other person.
