Okay time for another pronunciation poll: Longitude vs. Longitudinal, do you use a hard G (like Gift) or a soft G (like Giraffe)?
Both use hard G
39.1%
Both use soft G
55.2%
Longitude hard, Longitudinal soft
2.8%
Longitude soft, Longitudinal hard
2.8%
Poll ended at .

Every pronunciation guide I see has a soft G for "longitude" (with some differences between UK and US for whether the "tu" is like 'tube' vs. 'choob') but they only get into the UK pronunciation of "longitudinal" where it's a hard G

And it seems weird to me that you'd pronounce the G differently between those two different words, since they're, like, the same root?

@fluffy Seems odd to go for a J sound when the root word is LONG
@timrichards I don't make the US English pronunciation rules, I just live within them
