Choose the correct sentence to express that it is possible that it will rain tomorrow, but the weather forecast says it will be sunny.
Answers:
"Might" is used to express possibility, and "going to" is used to talk about the future based on present evidence (e.g., weather forecast). The correct sentence is "It might rain tomorrow, but the weather forecast says it is going to be sunny."
Auxiliary verb
If you've ever wondered why English asks Do you know? instead of Know you?, or how a single sentence can carry tense, aspect, AND voice (has been being cleaned), you've felt the work of auxiliary verbs. They're tiny words that quietly carry most of English's grammatical machinery — get them wrong and questions, negatives, and tenses all fall apart.
An auxiliary verb combines with a main verb to add grammatical meaning. The English auxiliaries are be, have, do, and the modal verbs (can, will, should…). They handle questions (Do you?), negation (don't), tense and aspect (has gone, is going), and passive voice (was eaten).
Modal verb
If you've ever struggled with the difference between You must do this (strong command) and You should do this (advice) — or It might rain (possible) and It will rain (certain) — you've felt how much modal verbs do in English. They're how the language signals certainty, obligation, possibility, and politeness, and getting them right is what stops your speech from sounding either pushy or wishy-washy.
A modal verb is an auxiliary — can, could, may, might, must, shall, should, will, would — adding meaning around ability, permission, possibility, obligation, or speculation. Always followed by the bare infinitive (can swim, never can to swim), and never inflected for person.
Verb
If grammar feels overwhelming, the fix is almost always to focus on verbs first. They carry the action, the time, the mood, and the voice — a single verb form decides whether your sentence reads as past or present, fact or hypothetical, active or passive. Get verbs solid and the rest of grammar suddenly looks much smaller.
A verb expresses action, state, or occurrence — the engine of every English sentence. Most verbs have five forms (base, -s, past tense, past participle, -ing); be has eight; modal verbs have fewer. Verbs carry tense, aspect, mood, and voice.
A2 | Elementary | Pre-intermediate
If you can order coffee, ask for directions, and tell someone what you did yesterday — but struggle the moment the conversation drifts into anything abstract — you're operating at A2. Knowing this matters: A2 is the level where most learners plateau because they reach for B2 material too early and burn out. Stay here and your foundations get unbreakable.
A2 is the elementary level in the CEFR framework, covering routine communication and the first wave of real grammar: past simple and continuous, present perfect, basic modal verbs, first conditional, and common verb-pattern rules.
Difficulty: Easy
If a textbook leaves you confused, sometimes the issue isn't the topic — it's that the practice material is layered with extra complications. Filtering by Easy strips that away. You get one rule at a time, in plain everyday language, with no trick questions. It's how you make a shaky foundation solid before stacking more on top.
The Easy difficulty tag marks beginner-level questions and challenges — typically A1 or early A2. Single-rule focus, short sentences, common vocabulary, one clear correct answer.
