It’s no secret. I am no fan of Latin macrons. Silly stumbling blocks, in my opinion.
I am not alone in this thought. Cheryl Lowe of Memoria Press doesn’t care for them either. Read her thoughts in this excellent article: https://www.memoriapress.com/articles/macron-or-not-macron/
Don’t even get me started on the ridiculous restored classical pronunciation.
In short, macrons don’t even show up in Latin until the 1600’s. How, then, did the Romans read Latin? Maybe they were just faking it.
Still, more people use them than people who don’t use them. Latin teachers, mostly. Well, as for those Latin teachers, I don’t know half of them half as well as I should like; and I like less than half of them half as well as they deserve. (Thanks, Bilbo.)
Nonetheless, if you do want to macron (though, why you would is a mystery to me) you now have some tools to do so. Thanks go to a Latin student who likes macrons more than I.
Here are is a link he recently donated to me. Happily, I donate it to others.
