télécopie

This is the English equivalent and is often used directly in French in informal contexts, though 'télécopie' is the proper French term.

This refers to the fax machine itself, the device used to send or receive a 'télécopie'.

This is a copy made with a photocopier, not transmitted over phone lines like a 'télécopie'.

Both relate to telecommunication, but 'téléphone' refers to the device for speaking, not sending documents.

'téléphone' is for voice calls, 'télécopie' is for document transmission via phone lines.

J'ai appelé ma mère au téléphone. (I called my mother on the phone.)

Both are methods of sending documents, but 'e-mail' is electronic mail via the internet, 'télécopie' uses phone lines.

'e-mail' is digital and internet-based; 'télécopie' is an older technology using telephone networks.

J'ai envoyé le document par e-mail. (I sent the document by email.)

Both are documents, but 'lettre' is a physical letter sent by post, whereas 'télécopie' is transmitted electronically.

'lettre' is a physical paper document; 'télécopie' is a transmitted copy of a document.

J'ai écrit une lettre à mon ami. (I wrote a letter to my friend.)

'Message' is a general term for information conveyed, which can include a fax, but 'télécopie' specifies the method.

'message' is the content; 'télécopie' is the specific type of document transmitted by a fax machine.

J'ai reçu un message important. (I received an important message.)

A 'télécopie' is a type of 'document', but 'document' is a much broader term.

'document' is any piece of written information; 'télécopie' is specifically a document sent by fax.

J'ai besoin de ce document pour la réunion. (I need this document for the meeting.)
