Could I describe a diary entry which was made to look genuine although in fact it was written specifically to illustrate language points in a text book as 'made for diary entry'? 

"Does this look like a made for diary entry to you?"

Thank you

Have a look at the word 'simulated'.

Best wishes, Clive
This doesn't work, PBF. You'll just have to write it out - unless someone else has a term.

Does this look like an artificially composed (fake, bogus, counterfeit, contrived) diary entry to you? Do you need to get the "language points" in there too??

Does this look to you like a diary entry created for demonstration purposes only?

- A.

Edit. Bravo, Clive! Why couldn't I think of that?

P.S. The only example of "made for" which is remotely similar (that I can think of) is a made-for-TV movie. But this is a very common expression which everyone understands. I don't think you can use "made-for-X" in general application. In other words, it's a movie but it's not really a [genuine] movie. It's a special-purpose movie. You'd have to say, "a made-for-teaching diary entry."
Students: Are you brave enough to let our tutors analyse your pronunciation?
Thank you for your replies, Clive and Avangi.

So would 'simulated' be the term I'm looking for here? I am more familiar with the verb 'to simulate' than the adjective 'simulated'. 

"Does this look like a simulated diary entry to you?" 

Thank you again 

I think that's the best we can do. I don't know how you can specify the purpose for which it was simulated (for teaching/demonstrating points of language) unless you explain it out in a separate phrase. - A.
How about "fabricated"?

Hi, A-S

I like Clive's better, because in my experience "fabricated" often simply means constructed/assembled, and not necessarily falsified or not genuine.

"Simulated," on the other hand, always means an imitation of the real thing.

You could surely say that PBF's entry is fabricated, but you could also say that of any diary or diary entry. (I agree we generally assume when a document is said to be "fabricated," that it's been falsified.)

Best wishes, - A.
Hi Avangi:
Here's the Random House definition for fabricate (Webster's is similar)

1. to make by art or skill and labor; construct: The finest craftspeople fabricated this clock.
2. to make by assembling parts or sections.
3. to devise or invent (a legend, lie, etc.).
4. to fake; forge (a document, signature, etc.).
and Simulate:

1. to create a simulation, likeness, or model of (a situation, system, or the like): to simulate crisis conditions.
2. to make a pretense of; feign: to simulate knowledge.
3. to assume or have the appearance or characteristics of: He simulated the manners of the rich.

So either might suffice in this situation.
I agree. "Fabricate" sometimes means "fake," and "simulate" always means "fake."
