B2 English Vocabulary: Words That Lift You Above Intermediate [2026]

B2 is the level where word choice starts to carry weight. At B1 you can make yourself understood with general vocabulary; at B2 you are expected to reach for the exact word instead of the nearest one. The difference between "a big change" and "a significant change" is small on the page but large in effect, and learning to make that upgrade, again and again, is most of what moves you above intermediate.

B2 is also the level many people are aiming for. In our test data it is the result for about 16% of the 193,751 people who complete the English level test, and among people who sit our dedicated B2 test, 56% reach the level, out of 2,593. That is a high pass rate for a demanding level, which tells you B2 is within reach with focused work. This guide presents B2 vocabulary as upgrade pairs: the general word you already know, and the sharper word that signals the level.

Upgrading importance

The words that make significance precise.

• important becomes essential, vital or "crucial" depending on strength. A vital repair, not just an important one.
• big change becomes significant or substantial. Sales showed a significant rise.
• small becomes minor or negligible. A minor delay, not a small one.

Upgrading good and bad

Where most learners rely on two tired words, B2 offers a scale.

• good becomes excellent, impressive or outstanding. An outstanding performance.
• bad becomes poor, severe or disappointing. A severe shortage.
• nice becomes pleasant, appealing or welcome. A welcome surprise.

Choosing along this scale is the clearest single marker of B2, because it shows you are grading your meaning, not just labelling it.

Upgrading feelings

Emotion vocabulary is where precision pays off fastest.

• happy becomes delighted, thrilled or content. I was delighted to hear it.
• angry becomes annoyed, frustrated or furious. She was furious about the delay.
• sad becomes disappointed, upset or miserable. He seemed upset.
• tired becomes exhausted or drained. I was exhausted after the shift.

Upgrading size and amount

The quantifiers that replace big and a lot.

• a lot of becomes a great deal of or numerous. Numerous complaints.
• very big becomes enormous or considerable. A considerable sum.
• enough becomes sufficient or adequate. Sufficient time to prepare.

Upgrading verbs

Precise verbs do the same work as precise adjectives.

• get becomes obtain, receive or achieve. She achieved a high score.
• show becomes demonstrate or reveal. The results demonstrate a clear trend.
• say becomes claim, state or argue. He argued that the plan was flawed.

Where B2 sits

B2 vocabulary is precision, not rarity. If you can trade general words for exact ones across importance, feeling, size and action, you are working at B2, whatever a word count says. The jump here builds directly on B1, so our guide to B1 vocabulary is a useful reference for the level just below.

Because B2 is the level universities and employers most often ask for, it is worth knowing precisely where you stand rather than assuming. Our English levels guide shows what B2 asks for next to the levels around it, so you can see whether B2 is behind you, within reach, or the next real target.
