Why did 実在 retain its old form when the 促音 was introduced?


Furthermore, are there any other words that retained their larger, pronounced
つ when this change occurred?

Edit: 仏像 seems to be another one.




It's because 在 (ざい) starts with a voiced sound (z). You usually don't see a
sokuon before voiced sounds, except in gairaigo.
