Possible to connect a guitar to my home cinema reciever?

Is it possible to connect a electric acoustic or plain old electric guitar into my av reciever?

Connection wise my only real option is phono (Don't think 1/4" to HDMI exists ) so will this be ample enough to carry the signal and allow the receiver to do the processing? Will a standard 1/4" to phono adaptor be fine? Will this create any negative effects on my speakers or amp?

Seriously you are better off getting a dedicated amp/speaker for this, you will possible destroy your amp and speakers..
Not a wise thing.
You can get cheapish guitar amp for next to nothing, and save your self the pain and tears off having your av gear fried.

Only my 2 cents worth.

Why exactly would it fry my gear?

I thought of it this way; sound is just sent as an electrical signal which is then taken and amplified by the receiver and then sent to the speakers (I think, anyway.) A guitar is just sending a signal like anything else, it's just the source of the signal that changes; instead of it being a pre-recorded sound sent from a CD player, for example, it is just taking the signal straight from the little magnet things under the strings.

Am I completely wrong? ( I honestly do have the most rudimentary and least-researched idea of how sound signals work) Does a guitar sent a huge current down the jack that would affect my system? I know you said that it would fry my system, I just want to know exactly why it would fry it.

Oh, I read something about distortion being bad for the speakers, but I have to return with the fact that I would be plugging a plain old electric acoustic in there with no effects, and that my speakers cope well enough with "Waters of Nazareth" by Justice played pretty loud.

The difference between AV speakers and PA speakers are very large indeed.
Imagine putting a truck engine (the guitar) in a mini, and throttling it, what would happen to the tyres (speakers) ??
This is as basic as I can give an example.
HT speakers are not designed to take a raw input of any musical instrument and be amped..
When you listen to a cd, they have been studio calibrated to be able to be best reproduced by Home hifi, not a raw feed as such as a guitar..
You are putting a guitar and letting the amp give the rawest signal, no mixing down of signal, or equalization..
IMO not the best thing you can do to a home amp and speakers.
The speakers are just not designed for such purposes.
As where a PA, say 8 inch cone or 10 inch, even 12 -15 can handle these extreme voltages, pure input quite easily, with an appropriate amp.
Two diff kettles of fish..
I know I am not explaining this properly, but I just would advise against doing such.
I have had a friend do a similar thing with a slide guitar and the speakers lasted 1 week.
Also remember that the output of the guitar, pre amp, is most likely not matched to the amp and you could possibly blow the input stage of the amp.
Just my 2 cents worth again..
1 more thing, they would have allowed guitar inputs in amps if they were designed for such instruments, but they don't for a reason.
