Ancient Punic Language

Hi there, it's me again - so successful last time I thought I'd ask another...

I'm writing something set in part in Ancient Carthage. I would like to use some of the language, which is apparently a dialect of ancient Phoenician. My understanding is that ancient Hebrew is a good analogue.

Can someone recommend a good book or course to learn Ancient Hebrew, preferably as cheap as possible?

Also, would Classical Latin be understood in Carthage? I know they and the Romans were enemies, but being a trading centre, I wonder whether some would be spoken anyway. Or would Greek be the better choice, (in which case I am in trouble as I have zero ancient Greek).

If anyone has any insights, please share! Thanks in advance!

Thanks guys! I'm more grateful than I can say.

I should probably explain the issue I have a little better. The book I'm writing is science fiction and deals with people who find themselves able to travel through the multiverse.

My narrative problem is that the heroine has been supplied with a very limited set of phrases in probably no more than eight languages to use in an emergency. There is only six weeks to teach her these things. Two of these languages do not exist in our world, or rather the dialect of one does not, but they are commonly spoken conqueror languages in
many other worlds.

The languages are:

Latin (Classical)
Cantonese (modern)
Spanish (early modern)
Hindi (modern)
Emisketan (an Indo-European language similar to Persian, not spoken in this world, modern)
Arabic (modern)
Russian (modern)
Para Etse-etse (Classical era - African click language not spoken in this world)

The phrases include things like, "I am the slave of a powerful man",
"My husband will pay you to escort me safely to the city", etc.
I think anything more elaborate is simply not going to be doable in the timeframe she has.

So I need a very vague knowledge of a Phoenician language I can construct simple conversations from and which will not cost me the earth to learn (the only Punic book I can find on Amazon is nearly £100 and presupposes knowledge of Canaanite languages generally).

Aramaic would be a little more authentic, but again, I need something I can get basically conversant in quickly and yet I can tinker with to make sound more Punic.

Hebrew seems to be better supported than Aramaic from a learning perspective, yet similar enough to be worth doing. I can also get Hebrew checked by someone else if I want, Aramaic would be trickier (and original Punic impossible). But I just want to be sure I'm not making a mistake. It would be nice to get it as right as possible in my time and money resources.

Ideally, I planned to have her able to get by (albeit very haltingly) in Latin and then pick up some Punic on the way to Gaul.

Basically, after all my chatter, I am just wondering if there is a compelling and as-yet-unforeseen-by-me reason why my current plan is doomed.

Thanks sir! Happily the lion's share of the section involves the heroine being on her own and is consequently internal monologue, but I just need enough dialogue for her to be able to carry out a couple of essential plot interactions.

Have ordered a starter's Hebrew book from Amazon, and shall see how I get on!
