One place to find every LexFizz reference tool — look up a single word, browse the common word list, check grammar terminology, or untangle words that everyone confuses. No sign-up, no ads, no limits.
English learners run into two very different kinds of questions: "What does this word mean?" and "Which of these two similar words do I need?" The Reference hub brings together four focused tools so you always know where to look. Each tool below links through to hundreds of individual entry pages, and every entry page links back here and to the related Grammar and Vocabulary hubs.
Deep-dive pages for individual words — definition, IPA pronunciation, example sentences, synonyms, antonyms and common mistakes.
Browse 563 high-frequency English words A–Z in one list, then click through to any word's full lookup page.
Clear definitions of grammar terminology — nouns, verbs, collocations, articles and more — with CEFR levels.
Hundreds of commonly confused word pairs explained side by side — affect vs effect, their vs there, lay vs lie and more.
The Reference hub is a single starting point for four separate LexFizz lookup tools: single-word pages (/word/), the Common English Words list (/words/), the Grammar Glossary (/glossary/), and the Confusing Words guide (/confusing-words/). Use this page when you are not sure which tool has the answer you need.
They sound similar but do different jobs. /word/ pages (singular) are individual deep-dive pages for one specific word — for example /word/ability/ — with a full definition, pronunciation, example table, synonyms, antonyms, common mistakes and its own FAQ. /words/ (plural) is the index page that lists all 563 of those word pages together in one browsable A-Z grid, so you can scan the whole list or search for a word before clicking through to its individual page.
Use the Glossary when you need to understand grammar terminology itself — what a noun, verb, collocation or article actually is. Use the Words list when you need the meaning of an everyday vocabulary word like "ability" or "benefit". The Glossary explains the building blocks of grammar; the Words list explains vocabulary in use.
Confusing Words is a guide to word pairs that learners (and even native speakers) frequently mix up — affect vs effect, their vs there vs they're, lay vs lie. Each entry compares two or three similar words side by side. The Glossary, by contrast, defines single grammar terms in isolation rather than comparing look-alike or sound-alike words.
If you already know the word you want to check, go straight to its /word/ page or search the /words/ list. If you keep muddling two similar words, check Confusing Words. If you do not understand a grammar term you saw in an exercise or textbook, check the Glossary. Most learners bookmark all four and switch between them as needed.
Yes. All four reference tools on LexFizz — Word lookup, Words list, Glossary and Confusing Words — are completely free with no sign-up, no account, and no limits on how many pages you view.
Yes. Every individual word page, glossary term page, and confusing-words entry links directly to relevant LexFizz exercises such as Flash Cards, Quiz, and Complete the Sentence, so you can move from looking something up to practising it immediately.
The Reference hub currently covers 563 individual word pages, a grammar glossary of core terminology, and hundreds of commonly confused word pairs — several hundred reference pages in total, all cross-linked to each other and to the Grammar and Vocabulary hubs.
Yes. Confusing word pairs such as affect/effect, fewer/less and its/it's are common error sources in exam writing tasks, and precise grammar terminology from the Glossary helps you understand examiner feedback and rubrics. Many learners use the Reference hub alongside the IELTS Prep section for targeted revision.
The hub links to four dedicated tools, each with its own index page and individual entry pages. Every entry page includes a short breadcrumb trail back to its index and to this hub, so you can always navigate back up a level or across to a different reference tool.
