This is not only correct, it's actually MORE correct. The current main answer is grammatically incorrect because "on" is needed.
I don't think so - native English speaker here - "I am more happy than I was yesterday" is grammatically correct.
DL accepted it. I want to be sure because I am not native English speaker.
"for certain days i'm more happy" if somebody can explain to me why I can't use "For certain" instead "On certain" or just "certain" in this case.
For certain/for sure is used when you want to say something is true. "For sure, he is a trustworthy fellow."
Hi, Jackie. 'happier' - piu' felice - is a comparison, it means more happy- happier than before, happier than yesterday, happier than you ...
More THAN happy is different, it's a casual phrase meaning very, very happy. No comparison with anything else - just really, really happy. (A: How is the ice cream? Happy? B: MORE than happy!)
Darn. Now I want ice cream.
Have a more-than-happy day. :)
