Why would "Your bag is more heavy" be incorrect?
Because of English rules.
More heavy doesn't exist, it's heavier.
Many short words apply that construction. (Eg. Happy/happier, naughty/naughtier, ...)
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.
So can i put lebih infront of every adjektiv to become “more“ of something? For example lebih senang, lebih lapar, lebih besar, lebih...
Your bag is heavier... Than what? There is something missing in this sentence
How do you say "heavier than", like "Your bag is heavier than my bag"
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.
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
I can't understand the male voice
"Your bag is more heavy." should be accepted.
