Linguabase vs. Oxford Languages

Different architectures for different problems.

The Core Difference

At a glance
Oxford sells lookup data—definitions and synonyms for embedding in products.
Linguabase is a complete vocabulary stack built for word games.

Oxford answers: “What does X mean?” and “What’s similar to X?”

Linguabase answers those too, plus: “How hard is this word?” “What hints work without sharing morphology?” “Which sense of X connects to which sense of Y?”

Traditional dictionaries and thesauruses are designed for word substitution—helping writers replace one word with another. Linguabase is designed for word games—validated vocabulary, difficulty rankings, readable definitions, short clues for gameplay, content filters, and semantic connections that power hints and exploration mechanics.

Words with Spaces

Deep Dive
Words with Spaces — an interactive essay on the half-million compound phrases missing from dictionaries.Traditional dictionaries exclude most compound phrases—not because they aren’t words, but because they contain spaces. “Boiling water.” “Saturday night.” “Best friend.” These function as single semantic units—they name things—but dictionaries leave them out. Oxford includes opaque idioms like “red tape” and “cold feet” (where meaning isn’t predictable from parts), but skips transparent compounds that are just as real.

The result: roughly half a million English expressions that function as words aren’t in any dictionary.

Oxford Linguabase
“hot dog” (opaque) ✓ ✓
“red tape” (opaque) ✓ ✓
“boiling water” (transparent) ✗ ✓
“front door” (transparent) ✗ ✓
“best friend” (semi-opaque) ✗ ✓

For word games, this matters. Players think in concepts, not spelling rules. If your game accepts “discombobulate,” it should probably accept “paper towel.”

Linguabase includes ~200K multi-word expressions—compounds, phrasal verbs, and collocations that traditional dictionaries systematically exclude.

Relationship Comparison

Oxford’s thesaurus is excellent at what it does — finding substitute words. But that’s a different problem than finding associated concepts.

"bridge" — Oxford (thesaurus): Synonyms you could substitute bridge1: span, overpass, viaduct, flyover, crossing... bridge2: connect, link, join, unite... "bridge" — Linguabase: Concepts the word evokes structure: span, arch, suspension, cantilever, viaduct, girder, abutment... card game: bidding, trump, slam, contract, partner, duplicate, rubber... guitar: luthier, saddle, pickups, fretboard, intonation... dental: crown, implant, prosthetic, false teeth, abutment... figurative: connection, gap, divide, reconciliation, transition...

Oxford helps writers find substitute words. Linguabase helps applications find where users’ minds might go—including senses (card games, guitar parts, dental work) that thesauruses don’t cover at all. See how we build sense-aware associations →

Definition Comparison

The clearest difference is in how definitions are structured.

Linguabase “spring”

The noun spring may describe the season following winter when days lengthen and plants start growing; a natural supply of water from the ground (mineral spring); or a device that returns to its original shape when force is removed. Spring also describes a lively quality, suggestive of the rebounding force of spring. To spring is to move suddenly and quickly, often upwards. An instance of this is also called a spring. Something that springs a leak suddenly starts leaking.
