Defining Communication: Meaning and Key Definitions

Every organisation – whether a small panchayat office or a sprawling multinational – runs on a single invisible current: communication. It is what turns a group of individuals into a coordinated team, a directive into action, and a policy into practice. Yet, for something so fundamental, communication is surprisingly difficult to pin down. Let’s unpack what communication really means, trace its roots, and examine how leading thinkers have defined it in the context of organisations and administration.

The origin of the word “communication” 🔗

To truly understand communication, it helps to begin at its linguistic source. The English word traces back to the Latin term “communis,” which means “common” or “shared.” According to scholarly work on the history of the idea, the word “communication” descends from the Latin noun communicatio, meaning a sharing or imparting, which stems from the root communis meaning common or public . The related Latin verb communicare literally means “to make common.”

This etymology is more than a linguistic footnote. It reveals the very soul of the concept. When two people communicate, they are not merely exchanging sounds or symbols – they are attempting to create something shared between them: a common understanding, a common purpose, or a common experience. As one etymological study notes, the word is derived from the Latin “communis,” which means to form a common ground of understanding, to share information, ideas or attitudes, and to impart or transmit information .

This idea of “commonness” is what separates genuine communication from mere transmission. A loudspeaker can transmit sound, but it cannot communicate unless the listener actually receives and understands the message.

What communication really means 🔗

At its most basic level, communication is the process of transferring information, thoughts, ideas, emotions, and opinions from one person (the sender) to another (the receiver) in a way that is understood. It is not a one-way broadcast but a two-way exchange that involves encoding, transmission, reception, and interpretation.

Consider a simple office scenario. A department head sends an email instructing her team to submit quarterly reports by Friday. If the team reads the email, understands the deadline, and acts on it, communication has occurred. But if the email is buried in inboxes, misinterpreted, or ignored, what took place was merely transmission – not communication. The distinction matters because organisations stand or fall on whether their messages actually land.

According to a widely cited management source, communication is best understood as a process. It begins with a sender who encodes the message and passes it through some channel to the receiver who decodes the message, and it is fruitful only if the message sent is interpreted with the same meaning by the receiver . In other words, communication is complete only when the receiver’s understanding matches the sender’s intent.

Key elements of communication 🔗

Every act of communication involves a few essential ingredients. The sender is the person who initiates the message. The message is the information, idea, or emotion being conveyed. The channel is the medium – a spoken word, a memo, an email, a gesture, or even silence. The receiver is the person who interprets the message. And finally, feedback closes the loop, signalling to the sender whether the message was understood as intended.

Without feedback, communication risks becoming a monologue. This is why modern administrators insist on two-way channels – open-door policies, regular review meetings, grievance redressal systems – rather than top-down directives alone.

Classical definitions of communication 🔗

To appreciate communication’s role in organisations, it helps to look at how scholars and practitioners have defined it over the decades. Each definition captures a slightly different facet of this rich concept.

Pfiffner: Communication as the heart of management 🔗

John M. Pfiffner famously described communication as the “heart of management.” This metaphor places communication at the centre of every managerial function – planning, organising, staffing, directing, and controlling. Just as the heart pumps blood to every part of the body, communication circulates information, instructions, and feedback through every layer of an organisation. Without it, management simply stops functioning.

Think about what a manager actually does all day. They give instructions, listen to concerns, negotiate with stakeholders, write reports, and attend meetings. Research cited in a widely used organisational behaviour textbook shows that communication dominates managerial work: 50% to 90% of a manager’s time is spent communicating, and communication ability is directly related to a manager’s performance . If communication is the heart, then a manager who cannot communicate is a manager who cannot manage.

Millet: Communication as the bloodstream of administration 🔗

John D. Millet took the biological metaphor further, describing communication as the “bloodstream of an administrative organisation.” This definition is particularly powerful in the context of public administration. A government department is a vast, multi-layered body with countless organs – ministries, bureaus, field offices, and citizens at the other end. Communication is what carries life-giving information through this body, ensuring each part knows what the others are doing.

When the bloodstream is clogged – when files pile up, messages get lost, or orders never reach the ground – the administrative body suffers. Policies fail to reach beneficiaries, grievances go unaddressed, and the entire machinery slows down. Healthy communication, by contrast, keeps every organ oxygenated and responsive.

Peter Drucker: Communication as mutual understanding 🔗

Management thinker Peter Drucker offered a more functional definition, describing communication as “the ability of various functional groups to understand each other.” This is a particularly useful definition for modern organisations, which are often divided into specialised departments – finance, marketing, operations, human resources, IT – each with its own vocabulary and priorities.

Drucker’s insight was that information transfer is not the same as communication. As a profile of Drucker’s work observes, he was intrigued by employees who knew more about certain subjects than their bosses or colleagues, yet had to cooperate with others in a large organisation . In Drucker’s view, real communication occurs only when departments with different perspectives arrive at genuine mutual understanding – when the engineer truly grasps what the marketer needs, and vice versa.

Webster: Communication as interchange 🔗

Webster’s dictionary offers one of the most widely cited definitions, describing communication as “the interchange of thoughts or opinions through words, letters, or messages.” This definition is deliberately broad, capturing the fact that communication can take many forms – spoken, written, symbolic, or even non-verbal. A standard reference in organisational behaviour elaborates on this, noting that communication is a process by which information is exchanged between individuals through a common system of symbols, signs, or behaviour .

The keyword here is “interchange.” Communication is not a one-shot event but an ongoing back-and-forth. Even a simple nod in response to a question is part of this interchange.

Other notable definitions 🔗

Several other thinkers have added their own nuances. Keith Davis defined communication as the transfer of information and understanding from one person to another. Louis Allen described it as the sum of everything a person does when they wish to create understanding in another’s mind. Peter Little viewed it as the process by which information is transmitted between individuals or organisations so that an understanding response results, as noted in a compilation of key definitions. The Oxford English Dictionary similarly defines communication as the action of conveying or exchanging information and ideas .

Across all these definitions, a common thread emerges: communication is not just about sending a message – it is about creating shared understanding.

Why communication is the lifeline of organisations 🔗

If we accept that communication is the heart and bloodstream of organisations, then its absence is fatal. Every organisational activity depends on it. Planning requires communication to gather inputs and share objectives. Organising requires communication to assign roles and coordinate tasks. Leading requires communication to motivate and inspire. Controlling requires communication to monitor progress and provide feedback.

An analysis of organisational communication highlights this clearly: communication is the means by which employees express themselves, air their grievances, and interact socially, and for many employees their workplace is a primary source of social interaction . Strip away communication and you are left with a collection of individuals, not an organisation.

Communication and employee satisfaction 🔗

Good communication does more than just coordinate work – it builds trust and loyalty. When employees feel informed about decisions that affect them, they become more engaged. Surveys consistently find that when employees think their organisations keep them informed about matters that affect them, and when they have access to the information they need to do their jobs, they are more satisfied with their employers . Research even suggests that organisations that improve their communication integrity can see meaningful gains in market value.

Communication in public administration 🔗

In government and public administration, communication takes on an additional dimension: accountability to citizens. A district collector must communicate upward to the state government, downward to block-level officials, horizontally with other departments, and outward to the public. Each of these flows matters. A breakdown in any one of them can lead to policy failure, public distrust, or administrative paralysis.

This is why institutions like the Department of Administrative Reforms and Public Grievances emphasise communication systems, grievance redressal mechanisms, and citizen charters as core tools for good governance. Communication is not a soft skill in public administration – it is the infrastructure of democratic accountability.

The essence of communication 🔗

Pulling all these strands together, we can distil communication down to a few core ideas. First, communication is rooted in the idea of commonness – it is an attempt to share something between minds. Second, it is a process, not a single act – involving encoding, transmission, decoding, and feedback. Third, it is only complete when mutual understanding is achieved. And fourth, it is the lifeblood of every organisation, from the smallest start-up to the largest government department.

Whether you see it as Pfiffner’s heart, Millet’s bloodstream, Drucker’s bridge between functional groups, or Webster’s interchange of thoughts, communication sits at the very centre of how human beings cooperate to achieve shared goals. Understanding its meaning is the first step toward mastering its practice.

What do you think? Reflect on your own experience: can you recall a moment when a message was transmitted but not truly communicated, and what was the cost? And among the classical definitions discussed above, which one captures the role of communication in your organisation most accurately – the heart, the bloodstream, or the bridge between functional groups?
