I like what you were going for, but I’m pretty sure “that” is “ðat”, and “þat” would be like “thot”, but with an “a”. I think.
The difference between them is ð is voiced, as in your throat is making sound and vibrating, whereas þ is voiceless, meaning it’s just air and your throat is still, but the rest of your mouth is in the same shape.
This is similar to how, for my accent at least, “v” and “f” are the same mouth shape, and one is voiced and the other isn’t.








I thought that heatsink and fan was a spindle of CDs! I thought that was an interesting place to store them I hadn’t seen before…
