The study of language using large collections of real text and speech, analysed computationally — which replaced the older method of relying on a linguist's intuition about what sounds acceptable.
A writing system built from a six-dot cell — two columns of three — where each character is a pattern of raised dots within that cell. Six positions give 63 possible combinations plus the blank, and
A system for writing at speaking speed — around 100 words a minute and above — by replacing the alphabet with symbols representing sounds rather than spellings, and by omitting everything a reader
Because swearing is not processed like ordinary vocabulary. It recruits emotional and automatic systems rather than the ordinary language pathway, which is why it behaves differently from every other
A language deliberately designed by a person or group rather than one that developed through use — usually abbreviated conlang. They fall into three purposes, and confusing them produces most of the
From the moment populations grew large enough that a single given name stopped identifying anyone — and across most of Europe the solutions converged on four sources, which between them account for
A formula estimating how hard a text is to read, almost always by combining sentence length with word length or syllable count, and outputting a grade level or a score. They are genuinely useful as a
Metre is the organised pattern of stressed and unstressed syllables in a line — the underlying pulse a poem is written against. Iambic pentameter is the most common English metre: five iambs, an iamb
Rhetoric is the study of persuasion — how language moves an audience — and Aristotle's three appeals are the oldest durable framework for describing how it works. They are not tricks; they are the
A network that lets you associate and get an address, but intercepts your traffic until you complete some action — accepting terms, entering a room number, watching an advert. The awkwardness
Reliable at country level, decent at city level in dense areas, and frequently wrong at any finer resolution — because an IP address contains no location information at all. Everything is inference
The Network Time Protocol — the mechanism by which almost every connected device keeps its clock correct — and the reason it matters is that a surprising amount of infrastructure fails outright when
Because the address space was fixed at 32 bits — about 4.3 billion addresses — in 1981, when the internet was a research network and nobody expected every household to hold dozens of connected
Because in most countries the physical access network is a natural monopoly — nobody is going to dig up every street several times over — so regulation separates the company that owns the wires from
A globally unique identifier for a network under a single routing policy — an ISP, a large hosting company, a university, a bank. It is the unit in which the internet's routing table is expressed,
Nobody, and several bodies with narrow remits — which is the accurate answer rather than an evasive one. There is no central authority; there are institutions that coordinate specific scarce
Three DNS-published records that together let a receiving mail server answer one question: was this message really sent by the domain it claims to come from? Email was designed with no sender
A set of protocols that lets a device on your network ask the router to open a port to itself, automatically and without authentication — which is exactly why it is convenient and why it is
The mechanism for saying "this certificate is no longer valid before its expiry date" — and it is the weakest part of the web's trust system, because the obvious designs all conflict with either
Brand architecture is how a company organises the relationship between its brands — the corporate name, product brands, sub-brands and endorsements — and it is the decision that determines whether
Three well-documented ways in which the presentation of a price changes how it is judged — because people evaluate prices comparatively, not absolutely, and have no independent sense of what most
Advertising delivered to internet-connected television screens — through smart TV apps, streaming services, set-top boxes and games consoles — bought like digital inventory rather than like broadcast
Moving marketing capability from agencies to employed teams — and the reason it cycles is that the trade-offs are genuine on both sides, so the correct answer changes as a company's circumstances
Three ways of paying for marketing services, each creating different incentives — and the incentive structure, more than the headline rate, determines what you actually receive. Retainer. A fixed
Rarely through the loyalty itself. Most programmes earn through a combination of margin funded by suppliers, changed purchase behaviour, unredeemed value, and — for the largest schemes — selling the
Yes — comparative advertising is lawful in the UK and EU, and it is deliberately permitted because comparison helps consumers. But it is permitted only on strict conditions, and failing any one of
Advertising in the UK sits under a co-regulatory system: industry-written codes enforced by a self-regulatory body, backed by statutory regulators who can act where self-regulation fails.
A performance model where a third party — a publisher, creator or comparison site — sends traffic to a merchant and is paid only when a defined action occurs, usually a sale. The mechanics are
A retailer selling advertising inventory against its own shopper data — on its website, in its app, in physical stores, and increasingly on other websites entirely. It has become the fastest-growing
Several distinct faults produce patches, and identifying which one you have determines whether it is fixable, whether it will spread, and whether it is worth repairing. Backlight bleed and clouding —
Almost always a clock problem — authenticator codes are generated from the current time, so a device whose clock has drifted produces codes the server rejects, and nothing about the account is wrong.
Because car infotainment systems are rarely updated while phones change constantly — so compatibility drifts apart, and a connection that worked for years can stop after a phone update with nothing
Because several separate things must all be working — the microphone, the network, the cloud service and the account — and the symptoms differ enough to identify which has failed. How it actually
Usually because the printer's driver has been withdrawn, blocked or superseded by an operating system update — and the modern answer is frequently that you no longer need one at all. What changed.
Because audio and video are processed along different paths with different delays, and unless something actively compensates, they drift apart — and the direction of the offset tells you where the
Because a word processor document is a set of instructions for laying out text, not a picture of a page — and those instructions are interpreted using whatever the receiving computer actually has
Almost always a time zone problem — and the specific mechanism determines whether the fault is yours, the sender's, or the software's. How calendar events store time. A well-formed event stores a
Because "sent" means your mail left your device — it says nothing about whether it was accepted, delivered or seen. Several things can go wrong after that point, and each leaves a different trace.
Because most messaging and social platforms recompress images on upload, and several also resize them — so what arrives is a smaller, more heavily compressed copy rather than the file you sent. What
It depends entirely on the country — and the crucial point is that there is no international standard, so a five-star hotel in one country is not comparable with a five-star hotel in another. The
Travel intended to leave a destination better than it was, rather than merely reducing the harm caused — a step beyond sustainable tourism, and one that is frequently claimed more than it is
The contract between you and the airline — setting out what each side is obliged to do, what happens when things go wrong, and the many things the airline is permitted to do that passengers assume it
A return itinerary where you fly into one city and out of another, covering the gap yourself — and it is frequently cheaper than two one-way tickets and occasionally cheaper than a conventional
Because airports need an enormous amount of flat land, generate noise nobody wants nearby, and — in some cases — because the name is a marketing decision rather than a geographical description. The
A flight arranged to bring people home when normal commercial services are unavailable — and who pays depends entirely on why it was needed, which is where expectations and reality diverge sharply.
By recognising that the signals are consistent and mostly about how a place acquires customers — a business relying on one-off visitors who will never return behaves differently from one relying on
It depends entirely on destination, activities, duration and your own health — and the important distinction is between vaccinations that are recommended for your protection and those required as a
Leaving a country briefly and re-entering to obtain a fresh period of permitted stay — a practice that was once widely tolerated and has been substantially curtailed almost everywhere. How it worked.
Who designates it and what the designation does. A national park is a national protected area with legal planning powers; a World Heritage Site is an international recognition with no direct legal
Travelling less far, less often and for longer, with fewer destinations per trip — an approach that emerged partly as a response to the environmental cost of flying and partly as a reaction against
