Choose the correct phrase to complete the teenager's interview with their grandfather.

Grandpa, ___ memorize everyone's phone numbers before smartphones were invented?

The correct answer is did you use to.

When asking a question about a past habit, we use the auxiliary verb did + subject + use to (base form). Remember, because did is already in the past tense, we drop the "d" from used!

Questions

Like many other Western European languages, English historically allowed questions to be formed by inverting the positions of verb and subject. Modern English permits this only in the case of a small class of verbs ("special verbs"), consisting of auxiliaries as well as forms of the copula be. To form a question from a sentence which does not have such an auxiliary or copula present, the auxiliary verb do (does, did) needs to be inserted, along with inversion of the word order, to form a question. For example:

  • She can dance. → Can she dance? (inversion of subject she and auxiliary can)
  • I am sitting here. → Am I sitting here? (inversion of subject I and copula am)
  • The milk goes in the fridge. → Does the milk go in the fridge? (no special verb present; do-support required)

The above concerns yes-no questions, but inversion also takes place in the same way after other questions, formed with interrogative words such as where, what, how, etc. An exception applies when the interrogative word is the subject or part of the subject, in which case there is no inversion. For example:

  • I go. → Where do I go? (wh-question formed using inversion, with do-support required in this case)
  • He goes. → Who goes? (no inversion, because the question word who is the subject)

Note that inversion does not apply in indirect questions: I wonder where he is (not *... where is he). Indirect yes-no questions can be expressed using if or whether as the interrogative word: *Ask them whether/if they saw him*.

Negative questions are formed similarly; however if the verb undergoing inversion has a contraction with not, then it is possible to invert the subject with this contraction as a whole. For example:

  • John is going. (affirmative)
  • John is not going. / John isn't going. (negative, with and without contraction)
  • Isn't John going? / Is John not going? (negative question, with and without contraction respectively)

Tag questions are formed with a special verb and pronoun subject: isn't it?; were there?; am I not?

Verb

A verb is a word that expresses an action, a state, or an occurrence — and it's the engine of every English sentence. Understanding how verbs work is foundational to everything else in English grammar, from forming questions to building complex sentences.

Verb Forms

Most English verbs have five inflected forms:

  • Base form (go, write, climb) — used as an infinitive, imperative, present subjunctive, and present indicative in all persons except third-person singular.
  • -s form (goes, writes, climbs) — used for the present tense, third-person singular (she writes).
  • Past tense (went, wrote, climbed) — also called the preterite.
  • Past participle (gone, written, climbed) — identical to the past tense for regular verbs, but often different for irregular verbs.
  • -ing form (going, writing, climbing) — serves as the present participle and gerund.

The verb be is a special case with more forms than any other English verb (am, is, are, was, were, been, being). Modal verbs like can, must, and should have fewer forms than typical verbs.

Main Verbs and Auxiliaries

Verbs in English often appear in combinations: one or more auxiliary verbs paired with a main verb.

  • The dog was barking very loudly.
  • My hat has been cleaned.
  • Jane does not really like us.

The first verb in the combination is the finite verb (it carries tense and agrees with the subject). The rest are nonfinite (infinitives or participles). Notice that these verbs don't always sit next to each other — as in does not really like.

Tense, Aspect, and Mood

English expresses tense (time reference), aspect (how an action unfolds over time), and mood (the speaker's attitude toward the action) mostly through verb combinations rather than word endings. That's why you'll encounter labels like "present progressive" or "conditional perfect" — these are specific tense–aspect–mood combinations built with auxiliaries.

Self-check: If you can change the time of a sentence by swapping one word (She runs → She ran), that word is the verb.

Habits and Routines

Quiz and questions containing descriptions of actions or activities that a person regularly performs. It includes the use of present simple and present continuous tenses to describe actions that are done regularly or currently happening, as well as the use of time expressions such as "usually", "always", "sometimes", and "never". This category also includes the use of adverbs of frequency such as "daily", "weekly", and "monthly" to indicate the regularity of an action.

Examples of common phrases used in this category include "I brush my teeth every morning" and "I usually have coffee at 8am." It also includes the use of "used to" and "would" to describe past habits.

A2 | Elementary | Pre-intermediate

CEFR A2 is the second level in the Common European Framework of Reference for Languages, often called elementary or pre-intermediate. If you're at this stage, you've moved beyond the basics of A1 and can handle simple, real-life communication — but you're still building the foundations you'll need for B1 and beyond.

What can an A2 learner do?

At A2, you can:

  • Understand everyday expressions related to familiar topics — personal details, family, shopping, work, and your local area.
  • Communicate in routine situations that involve a simple, direct exchange of information (e.g. ordering food, asking for directions, making small talk).
  • Describe your background and immediate environment in simple terms — where you live, what you do, what you need.
  • Read and understand short, simple texts like signs, menus, timetables, and brief personal messages.

Key grammar at A2

At this level, you're expected to be comfortable with several core grammar areas:

  • Past simple and past continuous — talking about completed actions and actions in progress in the past.
  • Present perfect — connecting past events to the present (I've visited London twice).
  • Basic modal verbs — expressing ability, permission, necessity, and possibility (can, must, should, have to).
  • Common question forms — both simple and slightly more complex (How long have you lived here?).
  • Articles and determiners — using a/an/the correctly, along with words like some, any, few, little.
  • Basic conditionals — first conditional and simple uses of if and wish.

You're also expanding your vocabulary through collocations (natural word pairings like make a decision or take a break) and learning to use gerunds and infinitives with common verbs.

How A2 differs from A1 and B1

Compared to A1, A2 learners can do more than just produce isolated phrases — you can link simple sentences and participate in short conversations. Compared to B1, you're still relying on familiar contexts and predictable language; handling unexpected topics or expressing opinions in detail comes at the next level.

Self-check: If you can describe your daily routine, talk about past experiences, and handle a basic conversation at a shop or restaurant — but struggle when the topic gets abstract or unfamiliar — you're likely at A2.
