About Grammar Solution Hub
Two languages, one kind of question
Whichever language you are writing in, the question is usually the same: is this right, and if not, what is? Everything here exists to answer that faster than a textbook and more precisely than a search result. Free to read, checked against published authorities, and honest about how it is made.

Two libraries, two different problems
One half explains a language you already speak. The other teaches one you are learning. Those are not the same job, and the guides are not written as if they were.

English Grammar & Writing
Written for people who already speak English and want to be sure. Adverbs, prepositions, tenses, antonyms, figures of speech — the points you look up mid-sentence because something reads slightly wrong and you cannot say why.

Spanish Grammar & Vocabulary
Written for learners, so nothing assumes you already know the term being used. Conjugation paradigms in full, the preterite-against-imperfect decision that decides whether a sentence sounds native, and vocabulary grouped by what you are trying to say.
Browse Spanish →The position behind all of it
A great deal of what gets taught as grammar is style preference wearing a stern face. Some of it is genuinely a rule — break it and the sentence stops being grammatical to a native speaker. Some of it is settled convention that varies between style guides. And some of it is one writer’s taste that hardened into folklore and now gets repeated as law.
Treating all three the same way is how people end up anxious about their writing without getting better at it. So the guides separate them, and when a point is genuinely disputed among the authorities, the guide says it is disputed and explains both positions rather than quietly picking one.
The same applies on the Spanish side. Usage differs between Spain and Latin America, and a guide that presents one as correct and the other as a mistake is teaching something false.
Rule, convention, or preference
- A rule — break it and the sentence is ungrammatical. Subject-verb agreement.
- A convention — settled practice that varies by style guide. The serial comma.
- A preference — one writer’s taste that became folklore. The supposed ban on splitting an infinitive.
How a guide gets made
Stated plainly rather than buried, because readers are entitled to know how what they are reading was produced.
Drafted with AI assistance
Guides are drafted and edited with the help of AI writing tools. We say so openly.
Checked against authorities
Every rule stated is verified against a published reference before it goes up.
Examples read for fit
Each example is checked for whether it actually demonstrates the point it claims to.
Corrected when wrong
Reader corrections are acted on, and each guide carries the date it was last checked.
What we check against
Neither language has a single authority everyone accepts, so a reference site has to say whose rules it is quoting.
Merriam-Webster
American spelling, definitions and usage notes.
Chicago Manual of Style
Punctuation and formatting in general English prose.
AP Stylebook
Conventions specific to news and web writing.
Real Academia Española
The reference point for Spanish grammar and orthography.
Unless a guide says otherwise, the English side describes American English, and where British and American usage genuinely differ — the serial comma, quotation mark placement, toward against towards — the guide says so rather than picking one and hoping you do not notice. On the Spanish side, where peninsular and Latin American usage differ, both are given.
Who writes it
How it is paid for
The site is free to read and funded by advertising. There are no paid guest posts, no sponsored guides, and no affiliate links — if a product is ever mentioned it is because it is relevant, not because it pays.
Advertisers have no input into what is published, no advance sight of guides, and no ability to have one changed or removed. What data our advertising partners collect is set out in the privacy policy.
When we get it wrong
We publish a great deal, about two subjects where people care about precision, so some of it will be wrong.
- Factual errors are corrected as soon as we can confirm them.
- A correction that changes the substance of a guide is noted at its foot, with the date.
- Typos and broken links are simply fixed.
Reader corrections are the cheapest quality control there is. Send one.
