Words that get confused

Pairs of terms that look alike and are not, with the difference that matters.

Updated on 13/08/2026

Many misunderstandings with suppliers, clients and auditors come from using as synonyms words that mean different things. These are the ones that cause the most confusion.

Signing and certifying

Signing expresses a will about a content: I accept it, approve it, acknowledge it. Certifying fixes that a file existed and has not changed since a date. You can certify something nobody signs, and sign something without certifying it.

Verifying and validating

Verifying checks that something is what it claims to be (the file has not changed, the signature is genuine). Validating decides that it serves your purpose. A certificate can verify perfectly and be useless to you because it has expired.

Approving and accepting

Accepting is receiving something as delivered. Approving is signing off on its content. When a process mixes them, someone ends up endorsing what they had merely received.

Important

The pair that causes most trouble is the second. "It is verified" and "it is validated" sound alike and mean different things in an audit: the first is a technical property of the file, the second is your decision, which you answer for.

Three more, more briefly

PairDifference in one line
Document and dataThe document is the file; the data is what was extracted from it
File and folderA file has status and process; a folder only groups
Expired and supersededExpired is stated by its date; superseded is decided by you

Watch out

And one that is not a pair but a trap: "certified copy" does not mean the same in every context. When someone asks for one, ask exactly what they need before sending anything — often a verifiable document is enough.

Why it is worth using them properly

Worth knowing

If one of these words is used differently in your company, write that down. That your sector says "validate" for what here is "verify" is not a problem as long as it is clear somewhere.

Does it matter day to day?

Usually not. It stops not mattering as soon as there is a third party or a dispute.

What is the commonest mistake?

Using "validated" to mean the file is intact.

Are there more terms?

Yes, in the general glossary and in each concept's own entry.

A real case
