2. to examine a source or speak to someone with the aim of discovering information

2.verbtransitive / intransitiveB1
Definition

to examine a source or speak to someone with the aim of discovering information

Example

Common Mistakes

Please check me the price of this item.
Please check what the price of this item is.
'check' is not a ditransitive verb; use a clause or phrase as the object, not an indirect object.

3.verbtransitiveB2
Definition

to stop or control something so that it does not get worse, increase, or continue

Grammar Patterns

Usage Note

Object is usually an abstract noun describing something undesirable or unwanted (growth, spread, decline, laughter, anger). More formal and literary than 'stop' or 'control'. Less common in everyday conversation.

Common Mistakes

I checked the fire from spreading by calling 911.
I called 911 to stop the fire from spreading.
In everyday speech, use 'stop' or 'prevent' rather than 'check' for concrete physical actions. 'Check' in this sense is more formal and often used for abstract trends.

Grammar Patterns

Common Mistakes

This sense is intransitive and takes 'with', not a direct object.

8.verbtransitive

  • check with a knight
  • check from two sides

Grammar Patterns

check + possessive + king

check + king + with + piece

Usage Note

When a king is checked, the player whose king is attacked must get the king out of danger on the next move — by moving the king, blocking the attack with another piece, or capturing the attacking piece.

9.verbtransitive
Definition

  • hit

    more general; can apply to any sport but lacks the specific meaning of a legal defensive check in hockey

Grammar Patterns

check + player

check + player + against + noun phrase

Usage Note

Body checking is a legal defensive move in ice hockey and lacrosse, but the rules limit how and where a player can be hit. Checking from behind is usually a penalty.

Synonym discussion

Sense: verb/1

All five words involve looking at something carefully, but they differ in thoroughness, purpose, and formality. 'Check' is the everyday word for a quick look to confirm correctness or safety — you check the time, check a tyre, check your email. 'Inspect' is more formal and methodical, suggesting a systematic, often official examination: a building inspector inspects a property for safety violations. 'Examine' is the most thorough; you examine a patient, a document, or evidence in detail, often to understand or diagnose. 'Verify' is formal and focuses on proving truth or accuracy against a standard: a scientist verifies experimental results. 'Scan' is the quickest — a rapid, often visual survey for a specific target: you scan a crowd for a friend's face. 'Review' suggests looking back over something already done to assess or improve it: a manager reviews a report before submission. For everyday checking of routine things — homework, email, a shopping list — use 'check.' For official or detailed scrutiny, prefer 'inspect' or 'examine'; for confirmation against a reference, use 'verify.'

Etymology

PersianArabicLatinFrenchEnglish

The word 'check' entered English through the game of chess. It traces back to the Old French word 'eschec', which came from Medieval Latin 'scaccus', which in turn came from Arabic 'šāh', borrowed from the Persian word 'šāh' meaning 'king' — the very same root found in 'checkmate' (from Persian 'šāh māt' meaning 'the king is defeated'). In chess, calling out 'check!' warned the opponent that their king was under attack. From this, the idea of 'stopping or controlling' grew: a king in check is restrained. The meaning of 'examining or verifying' developed in the 16th century, from the concept of checking a list against a reference to confirm accuracy. The financial sense (American 'check' / British 'cheque') appeared in the 18th century as a written order that could be 'checked' for fraud. The square-pattern sense ('checkered', 'checks') comes from the chessboard itself, whose alternating squares gave the pattern its name.
