I'd always said TRIH-fid to myself, but TRY-fid makes more sense if
maybe it refers to a partition into three.

You might sound funny at the ballpark if you yelled, "Look at that! A
TRY- ple play!"

Maybe so, but if you've studied English in this country as long as I
have, you know that the language is not exactly straightforward in
either spelling or pronunciation!

I guess it depends on who you like. American Heritage says "TRY-fid" and
Merriam Webster says "TRI-fid".
