Roommate 2: "_________________________. It's going to smell terrible in here."
Roommate 1: "I haven't washed the dishes from last night, either."
Roommate 2: "_________________________. We are terrible at adulting today."
Roommate 1: "Uh oh, I didn't take out the trash this morning."
Roommate 2: "Neither did I. It's going to smell terrible in here."
To agree with a negative statement in the past simple (like "didn't take"), we use "Neither + did + subject".
Roommate 1: "I haven't washed the dishes from last night, either."
Roommate 2: "Neither have I. We are terrible at adulting today."
To agree with a negative statement in the present perfect (like "haven't washed"), we use "Neither + have/has + subject".
English grammar
Grammar vs vocabulary: vocabulary gives you the words; grammar gives you the system for combining them into meaning. Knowing 10,000 words without grammar produces incoherent sentences. Knowing grammar with limited vocabulary produces clear, correct sentences about fewer topics. Both matter — but grammar is the framework.
English grammar is the complete rule system: parts of speech, phrase and sentence structure, tenses, agreement, word order, and punctuation.
Diagnostic: if your sentences are understood but "sound wrong" → grammar issue. If you can't find the right word → vocabulary issue. If both → start with grammar.
English Grammar Basics
Basics vs intermediate/advanced grammar: if you're unsure whether to study articles or conditionals, tense basics or reported speech — you need to check whether your foundations are solid first. Basics covers everything up to A2.
English Grammar Basics groups the core building blocks: nouns, verbs, adjectives, prepositions, present/past tenses, questions, and negation.
Diagnostic: if you still hesitate over she don't vs she doesn't, or a vs an — start here. Master these and intermediate topics stop feeling random.
Habits and Routines
Used to vs would for past habits: both describe repeated past actions, but used to works for states AND actions (I used to live there), while would works only for actions (I would walk to school). You can't say I would live there for a past state — that changes the meaning to a conditional.
Habits and routines combines present simple + frequency adverbs (current habits) with used to/would (past habits that have stopped).
Diagnostic: is it a past state (live, know, have)? → only used to. A past repeated action (walk, visit, bring)? → either used to or would.
Humor
Humor vs serious practice: both teach the same rules. The difference is engagement — funny material keeps you coming back and creates stronger memory hooks. If dry drills bore you into quitting, humorous practice is more effective because you actually do it.
The Humor tag filters for entertaining practice: silly contexts, wordplay, absurd examples — all testing real grammar rules underneath.
Diagnostic: if you find yourself dreading practice → try filtering by Humor. If you're preparing for a formal exam and want serious register → filter it out.
A2 | Elementary | Pre-intermediate
A2 vs B1: A2 handles routine transactions and simple past narration. B1 handles connected discourse, explaining reasons, and understanding main points in clear standard speech. If you can tell what happened but not why it matters, you're still A2.
A2 is the elementary level of the CEFR: past simple, present perfect, first conditional, basic modals, and routine communication about familiar topics.
Diagnostic: can you link ideas with because, although, so that and hold a conversation beyond scripted topics? No → A2. Yes → moving into B1.
Easy
Easy vs Medium vs Hard: Easy = one rule, obvious answer, A1–A2. Medium = one rule but realistic distractors, A2–B1. Hard = interacting rules, edge cases, B2+. Start Easy to check you have the basics before moving up.
The Easy tag filters for single-rule, short-sentence, common-vocabulary challenges designed for beginners or for anyone wanting a confidence check on fundamentals.
Diagnostic: if you get Easy questions wrong, stay here — your foundations need work. If they feel trivial, move to Medium.
