"Tas kamu lebih berat."

Translation: Your bag is heavier.

Why would "Your bag is more heavy" be incorrect?

[DarkHylian]

Because of English rules.

More heavy doesn't exist, it's heavier.

Many short words apply that construction. (Eg. Happy/happier, naughty/naughtier, ...)

[DarkHylian]

By the way, heavier is a comparative word, for me the sentence lacks somewhat to compare.

"Your bag is heavier than my bag"
Tas kamu lebih berat dari tas aku.

[DariaFrank5]

So can i put lebih infront of every adjektiv to become “more“ of something? For example lebih senang, lebih lapar, lebih besar, lebih...

[Coco726609]

Your bag is heavier... Than what? There is something missing in this sentence

[INalsGio]

How do you say "heavier than", like "Your bag is heavier than my bag"

[noey536981]

There is nothing incorrect about "more heavy." More heavy and heavier are equivalent. This is taught in American schools, and even in SAT prep material.

[RamenDutchman]

This was taught to me as incorrect English, and something to avoid!
Granted, I learned English as a second language at middle school, I'm just surprised that it's so different

"Your bag is more heavy." should be accepted.
