Reading an answer on another Stack Exchange site I've discovered the word "trilean", which I had never heard of. I understand its meaning (the context is computer science; boolean logic has two values, "true" and "false", while trilean logic has three, namely true, false, and something else), but I don't know how to pronounce it, and it is such a niche word that dictionaries don't report it: a search on Onelook doesn't find anything.
Is "tri" pronounced /traɪ/ (as in "triangle") or /trɪ/ (as in "trilogy")? The pronunciation of the prefix "tri" is quite tricky. If I had to guess I'd go for /trɪ/ as in trilogy, but I'm not sure at all.
Also, how do you pronounce "lean" in this case? I expect it to be as in "boolean", and not as in "lean". That is, lee-uhn (two syllables), and not leen (one syllable).
