What does checking mean?
Checking is the act of examining something closely in order to confirm that it is accurate, complete, safe, or in good order. It functions both as a noun naming this activity — as in 'a careful checking of the documents' — and as the present participle of the common verb 'check', which covers everything from verifying facts and inspecting luggage to restraining an impulse. The word carries connotations of diligence, caution, and quality control: fact-checking safeguards journalism, spell-checking polishes writing, and double-checking signals extra care where mistakes would be costly. Its history is surprisingly colourful, reaching back through Old French to the Persian word for 'king', since the original sense involved threatening the king in chess. From that single strategic manoeuvre, English developed a family of words including check, cheque, and checkmate, making 'checking' a small window into how metaphor spreads through language.
The action of examining something to verify its accuracy, condition, or completeness.
"Careful checking caught the typo before publication."
Typically uncountable; used most often in formal or procedural contexts such as proofreading, auditing, and quality control.
Present participle of 'check': to examine, test, or verify something; to stop or restrain.
"He was checking the tyre pressure when the phone rang."
'Checking' traces back to the Persian word for 'king' — because in chess, checking the king means threatening it, and every other sense of 'check' grew from that one royal move.

Etymology of checking
The word derives ultimately from the Persian 'shah' (king), which passed into Arabic and then Old French as 'eschec', referring to the chess move that threatens the king. English adopted it as 'check' by the late Middle Ages, and the sense broadened metaphorically from 'restraining the king' to 'stopping or verifying' anything at all. The noun 'checking' arose as the verbal action form, while related terms such as 'checkmate' (Persian 'shah mat', 'the king is dead') and the financial 'cheque' share the same origin.

How checking is actually used
As a noun, 'checking' is usually an uncountable gerund referring to the activity of verifying ('careful checking is required'). In American English, 'checking account' denotes a bank account for daily transactions, while British English uses 'current account'. The chess sense is technical and mostly confined to game commentary.
Easily confused with checking
'Cheque' is the British spelling of the written bank-order noun only, whereas 'checking' is the act of verification and never refers to a banking document.
