Help the confused alien visitor complete his observation log about Earth.

"Humans are strange. When it rains, they open colorful umbrellas to keep ___ heads dry, but they let their shoes get completely soaked!"

The correct answer is their.

Their is a possessive adjective used before a noun ("heads") to show that the heads belong to "them" (the humans). "Theirs" is a pronoun and cannot be placed right before a noun.

Adjective

An adjective is a word that describes or modifies a noun or pronoun, giving more information about its qualities, state, or identity. Adjectives are one of the core parts of speech in English, and you use them constantly — to describe people, objects, feelings, and ideas.

What adjectives do

Adjectives typically answer questions like What kind?, Which one?, or How many? They can appear in two main positions:

  • Before a noun (called attributive position): a tall building, fresh coffee, three students
  • After a linking verb (called predicative position): The soup is hot, She seems tired

Some adjectives work in only one position. For example, main is almost always attributive (the main reason), while asleep is almost always predicative (The baby is asleep).

Examples

  • ✅ She wore a red dress. (red modifies dress)
  • ✅ The exam was difficult. (difficult follows the linking verb was)
  • ❌ She wore a redly dress. (Adverbs like redly don't modify nouns.)
  • ✅ He gave me useful advice. (useful modifies the uncountable noun advice)

Adjective order

When you stack multiple adjectives before a noun, English follows a conventional order: opinion → size → age → shape → colour → origin → material → purpose. For example, a lovely small old round brown French wooden serving table — though in real life you'd rarely pile up that many.

Self-check: If your sentence sounds awkward with two adjectives before a noun, try swapping their order. The version that "sounds right" usually follows the standard sequence.

Adjectives vs. determiners

Words like the, this, my, and some were historically grouped with adjectives, but modern grammar classifies them as determiners. Unlike true adjectives, determiners don't have comparative forms (bigger works, but *more the doesn't) and occupy a fixed slot before any adjectives.

Comparatives and superlatives

Most adjectives have comparative and superlative forms used to compare things:

  • tall → taller → tallest
  • expensive → more expensive → most expensive

Possessives

In English, possessive words or phrases exist for nouns and most pronouns, as well as some noun phrases. These can play the roles of determiners (also called possessive adjectives when corresponding to a pronoun) or of nouns.

For historical reasons, this case is misleadingly called the possessive (case). It was called the genitive until the 18th century and in fact expresses much more than possession. Most disagreements about the use of possessive forms of nouns and of the apostrophe are due to the erroneous belief that a term should not use an apostrophe if it does not express possession.

In the words of the Merriam-Webster Dictionary of English Usage:

The argument is a case of fooling oneself with one's own terminology. After the 18th-century grammarians began to refer to the genitive case as the possessive case, grammarians and other commentators got it into their heads that the only use of the case was to show possession. ...

This dictionary also cites a study in whose samples only 40% of the possessive forms were used to indicate actual possession.

Nouns, noun phrases, and some pronouns generally form a possessive with the suffix -'s (apostrophe plus s, but in some cases just by adding an apostrophe to an existing s). Personal pronouns, however, have irregular possessives, and most of them have different forms for possessive determiners and possessive pronouns, such as my and mine or your and yours.

Possessives are one of the means by which genitive constructions are formed in modern English, the other principal one being the use of the preposition of.

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.
