Using technology & progress words in English
Emerging-technology vocabulary is built almost entirely from compounds, and the interesting question is how English joins them: machine learning stays two words, self-driving takes a hyphen, and cryptocurrency has fused into one. This page sets out the pattern, which is more predictable than it first appears, and covers a Greek plural still alive in the field.
What to watch out for
Compounds open, hyphenate or close by age and position
New compounds usually start as two words, acquire a hyphen when used before a noun, and eventually close up. So machine learning is open as a noun but hyphenated as a modifier — a machine-learning model — while self-driving and fibre-optic are hyphenated because they modify, and cryptocurrency and blockchain have already fused. When in doubt, hyphenate before the noun and leave it open after.
Countability splits this vocabulary
Cryptocurrency is countable when you mean particular ones — several cryptocurrencies — and uncountable for the category. Blockchain, bioengineering and cybernetics are uncountable, and the last takes a singular verb like other -ics fields. Automaton keeps a Greek plural: automata, though automatons is also accepted.
British spellings persist even in new words
Fibre-optic keeps the British -re, where American English writes fiber-optic. Digitise, virtualise and modernise take -ise in the British forms used here. Note also that augmented reality and genetic engineering remain stubbornly open as two words despite decades of use, which shows how uneven the closing process is.
Words learners mix up
Technology writing is full of words that sound like neutral description and are actually claims — about how soon something dies, how the future will go, and what a product can do. These three clusters are where the claims hide.
Ageing out of use
| Word | What it actually means | In a sentence |
|---|---|---|
| obsolescent | Becoming obsolete — the process is under way but not finished. The rarer, more precise of the pair. | An obsolescent standard still in limited use. |
| obsolescence | The noun for that process. Note the famous compound planned obsolescence, designing something to fail or date. | Built-in obsolescence shortens every upgrade cycle. |
| redundant | In engineering, a deliberate spare that exists so a failure is survivable — a compliment, not a criticism. | The system has three redundant power supplies. |
| retrofit | Fitting new technology into something that already exists. Both noun and verb, and the point is that you did not start again. | They retrofitted the fleet with new sensors. |
| leapfrog | Skipping a generation of technology entirely rather than upgrading through it. | Several countries leapfrogged landlines altogether. |
Redundant is the trap: in British employment English it means a post has been removed, but in engineering it means a backup exists — a redundant server is a good thing. Only context separates them, and the two senses are almost opposite in value.
The vocabulary of predicted futures
| Word | What it actually means | In a sentence |
|---|---|---|
| utopia | An imagined perfect society. From Greek meaning no place — the joke in the coinage is that it does not exist. | A technological utopia that never arrived. |
| dystopia | Its opposite: an imagined future where things have gone badly wrong. The dominant mode of modern tech fiction. | The novel is a surveillance dystopia. |
| singularity | The hypothesised point at which machine intelligence exceeds human control. Speculative and heavily contested. | Predictions of a coming singularity. |
| moonshot | A hugely ambitious project with a real chance of failing. From the Apollo programme, now standard corporate usage. | The company calls it a moonshot project. |
| frontier | The edge of what is currently possible. A metaphor that frames research as territory to be claimed. | The next frontier in battery chemistry. |
None of these is neutral. Singularity asserts a prediction, moonshot flatters a budget request, and frontier imports the language of exploration and settlement. In an essay, attribute them — what its advocates call a moonshot — rather than adopting them.
Engineering adjectives: what is actually being promised?
| Word | What it actually means | In a sentence |
|---|---|---|
| modular | Built from separate parts that can be replaced or rearranged independently. Testable and specific. | A modular design that takes third-party parts. |
| interoperable | Able to work with other systems, usually because it follows a shared standard. The strongest claim here. | The formats are fully interoperable. |
| seamless | Feels like one continuous experience with no visible joins. About perception, so much harder to verify. | A seamless transfer between devices. |
| streamlined | Simplified and made more efficient. Vague in a product description — ask what was removed. | A streamlined setup process. |
Modular and interoperable can be checked against a specification; seamless and streamlined describe how something feels and are the marketing end of the list. That is the same test worth applying to any adjective in a product announcement.
Collocations that sound natural
Technical writing pairs these nouns with a very narrow set of verbs and adjectives, and most of the pairings are about quantity — how much, how fast, how little delay.
obsolescence
planned obsolescencebuilt-in obsolescencetechnological obsolescenceaccelerate obsolescence
Planned and built-in are the two fixed modifiers, and both are accusations aimed at manufacturers.
latency
low latencyreduce latencynetwork latencylatency spikes
Uncountable, and the desirable direction is low — never fast latency, which reverses the sense.
iteration
the next iterationrapid iterationeach iterationiterate on a design
Countable. In software it means one cycle of improvement, not one copy.
throughput
increase throughputmaximum throughputthroughput of the system
Uncountable, one word. It measures how much passes through per unit of time, so it is not a synonym for speed.
implant
a medical implantimplant a devicea cochlear implantimplant rejection
Stress moves: the noun is IM-plant, the verb im-PLANT — the same pattern as record and export.
propulsion
a propulsion systemion propulsionthe means of propulsion
Uncountable, and it names the method of producing motion rather than the motion itself.
Formal, neutral or informal?
This vocabulary divides into working technical terms, speculative words borrowed from fiction, and a set of borrowings whose confidence outruns the evidence. Mixing the three is what makes technology writing sound credulous.
- self-driving / autonomous / driverlessGraded claimsNot interchangeable. Driverless says nobody is at the wheel; self-driving is the popular term for a range of assistance levels; autonomous is the engineering word and is normally qualified by a level number. Reporting a manufacturer’s claim, use their exact term.
- cyborg / automatonFiction · datedCyborg — a being part organic, part machine — belongs to science fiction and cultural theory rather than engineering. Automaton is older still and now means a mechanical figure, or figuratively a person acting without thought.
- terraformingSpeculativeAltering a planet to make it habitable. Entirely hypothetical, and a term from fiction that has entered serious discussion — worth marking as speculative when you use it.
- singularityContestedHas a precise meaning in mathematics and physics and a speculative one in futurism. In the second sense many researchers reject it outright, so it should be attributed rather than asserted.
- gamificationJargonAdding game mechanics — points, streaks, levels — to something that is not a game. Standard in product and education writing, still jargon outside them, and British English spells it with -isation in its relatives.
- moonshotCorporate metaphorNow used for any ambitious internal project, which has thinned it considerably. In an essay, a high-risk long-term project says the same thing without the borrowed glamour.
- server farmInformal · establishedA large collection of servers in one building. Fully understood, though formal writing says data centre — note the British -re.
- futuristJob title · scepticalSomeone who forecasts long-term change professionally. British readers tend to hear it with mild scepticism, so analyst or researcher is safer where the person has a track record.

- Quantum computing remains largely experimental.
Questions about technology & progress vocabulary
When do technology compounds take a hyphen?
The general rule is positional. Hyphenate a compound when it comes before the noun it modifies — a machine-learning model, a self-driving car, fibre-optic cable — and leave it open when it follows the verb: the car is self driving is rare, but the model uses machine learning is standard. Over time, frequently used compounds close up entirely, which is how cryptocurrency, blockchain and smartphone became single words. Where a dictionary already shows a closed form, use it.
Is "cryptocurrency" countable?
Both, depending on what you mean. As a category it is uncountable: investment in cryptocurrency has fallen. When you mean particular currencies it becomes countable: Bitcoin and several other cryptocurrencies. This is the same pattern that governs technology and innovation — uncountable for the field, countable for individual instances. Blockchain behaves slightly differently and is usually uncountable when it names the technology, but countable when you mean a specific ledger.
What is the plural of "automaton"?
Automata is the Greek plural and is standard in technical, mathematical and philosophical writing — finite-state automata. Automatons is also perfectly acceptable in general English and is more common when the word is used figuratively of people behaving mechanically. This is typical of Greek and Latin borrowings in English: the classical plural survives in the technical field where the word is a term of art, while the regular English plural takes over in ordinary use.
