The language of simplicity is widely advocated and rarely examined. The advice to write simply — to use short words, short sentences, plain vocabulary — is given so consistently across writing guides, style manuals, and editorial feedback that it has come to function as a baseline requirement rather than a considered choice. Be clear. Be direct. Avoid complexity. This advice is not wrong, but it is incomplete, because it treats simplicity as though it were a default — as though plain language were the natural state of writing and complexity were something added on top of it.
The reality is more interesting. Simplicity in language is a choice, made against available alternatives, with its own costs and limitations. Understanding what the language of simplicity actually does — what it makes possible, what it forecloses, and when it is genuinely the right choice — is more useful than treating it as an unconditional virtue.
What Simplicity Does Well
The language of simplicity does several things exceptionally well, and these are the reasons it is so consistently recommended.
It makes the argument accessible. A piece of writing that uses plain vocabulary and short sentences can be read by a wider range of readers than a piece that assumes specialist vocabulary or comfort with complex syntax. This is not a trivial advantage — if the argument is worth making, it is worth making to as many readers as possible, and simplicity is one of the most reliable routes to accessibility.
It exposes the thinking. A plain sentence cannot hide behind its own complexity. If the thinking is muddled, the plain sentence will show that — there is no ornament to conceal it. This is what Orwell meant when he argued that the English language becomes ugly and inaccurate when the writer has something to conceal. Simplicity strips that concealment away, which makes it the natural choice for a writer who is confident in their thinking and wants to demonstrate that confidence rather than disguise uncertainty.
It creates pace. Short sentences move quickly. A piece that needs to cover a lot of ground efficiently — that has a lot to say and limited space to say it — benefits from the pace that plain language creates. The reader moves through the material without friction, which is the right experience when the material itself is what the writer wants to dominate the reader’s attention.
What Simplicity Cannot Do
The language of simplicity is not suited to every task, and the writer who treats it as universally appropriate produces writing that is clear but sometimes impoverished.
The most significant limitation is complexity of thought. Some ideas are genuinely complex — they involve multiple conditions, qualifications, and relationships between things that resist compression into simple sentences without distortion. The sentence that subordinates a clause is not always doing so out of affectation; it is sometimes doing so because the relationship between the main clause and the subordinate clause is part of what the sentence needs to convey. Simplifying it loses that relationship, and the reader receives a cleaner sentence that says something slightly different from what was meant.
The second limitation is register and relationship. Very plain language in a context that calls for something more considered can read as dismissive or inappropriate — as though the writer has not taken the subject or the reader seriously enough to bring more care to the prose. A letter of condolence written in the style of a text message is simple in the wrong sense. The register is part of the communication, and simplicity in register can be as much a failure as simplicity in vocabulary is sometimes a virtue.
The third limitation is rhythm and texture. Long prose that is uniformly simple tends to lose texture — it becomes flat in a way that affects the reader’s engagement even when the argument remains clear. The varied sentence — short alongside long, simple alongside complex — creates a rhythm that plain language alone cannot. A piece that is unvaryingly simple in its sentence structure is a piece that has sacrificed rhythm for clarity, and clarity purchased at the cost of rhythm is not always a good trade.
When Simplicity Is a Choice and When It Is an Evasion
There is a kind of simplicity that is genuinely chosen — that has considered the alternatives and selected plain language because plain language is the right tool for this task, this reader, this argument. And there is a kind of simplicity that is an evasion — that reaches for plain language not because it serves the work but because complexity is harder to achieve and easier to avoid.
The second kind of simplicity produces writing that is clear about what it is saying and thin about what it is thinking. The short sentence that makes a point without developing it. The plain vocabulary that skirts the more precise word because the more precise word requires explanation. The accessible argument that is accessible partly because it has not gone deep enough to encounter the difficulty that genuine depth involves.
The test is whether the simplicity is serving the thought or limiting it. Plain language that renders a complex thought clearly is a genuine achievement. Plain language that renders a simple thought clearly is merely competent. And plain language that avoids complexity because complexity is hard is not simplicity — it is evasion wearing simplicity’s clothes.
The language of simplicity is one of the most valuable tools in a writer’s repertoire, and one of the most easily misused. Used deliberately, it makes arguments accessible, exposes thinking, and creates pace. Used as a default — as a substitute for the harder work of finding the right language for the right thought — it produces writing that is easy to read and easy to forget.
Simplicity chosen is a virtue. Simplicity defaulted to is a missed opportunity.
