I know spending a couple hours poking at a glossary and the Wikipedia page for a language is not the way to do translation, and Google Translate wasn't a help here, so I'm pretty sure I didn't get this right on the first try, but ... anybody here know enough Gothic to be able to tell whether this is anywhere close to what I'm trying to say?

Intended: "If you can read this, you might be a Goth," or word-for-word, "If thou art able this to read, thou Goth maybe art." Did I even come close? Is this the right word order?

(The first line is in the Gothic script, the second is Elder Futhark runes because apparently Gothic was written in that until Bishop Ulfilas decided to translate the Bible into Gothic (and maybe invented the Gothic script for the purpose?), though I may have picked the wrong runic alphabet, I'm not sure. The third is the Roman-alphabet transliteration that the glossary I found and all the grammar notes I saw are written in. Except for the Roman 'th' mapping to a single letter in the other two alphabets, all three should match letter-for-letter, unless I goofed there. If you read this on some mobile devices, only the Roman-alphabet version might be visible.)

I woke up yesterday (Sunday) with the notion that I needed this, in Gothic, on a card. I don't know why my brain does that. But as a result I learned some interesting things about Gothic (such as having dual forms for pronouns and verbs, but only singular and plural for most nouns[*]), I discovered that people are coining new Gothic words (e.g. "email", "bitcoin", "dictionary"), and I had an odd moment where I saw "Gothic email", almost parsed it correctly, then went, "Wait, I haven't learned this alphabet yet -- WTF?" (I guessed "e-book" instead of "email", so I don't get full credit, but I caught that the word was "ebooks" and recognized the "bokos" part from "dictionary" in that glossary being "waurdabokos". Gothic 𐍉 and Elder Futhark ᛟ looking so similar helped a lot.) Something has definitely shifted in the language-processing part of my brain in the last few years. Time to see whether I've gotten any better at learning languages (as opposed to just playing around with phrases). Maybe brush up on my French, and have yet another stab at Modern Greek.

[*] For example, in nominative (subject) case: thou -> thu; you two -> jut; all y'all -> jus. That's a y-sound 'j', not a zh-sound 'j', so the thou/you parallel to English is there. The accusative (direct object) case doesn't feel as English-like though: thee -> thuk; you two -> igqis; all y'all -> izwis.
