more, ~er もっと

One easy way to say "MORE" or "-er" is to add a もっと motto before the thing you want to emphasis. This is one of the rare times that the word order is the same with English - or at least with the more part! Relish the moment (while you can) 

{ motto ~ = more ~ }

もっと　ピーマン　を　食べなさい。 motto pi-man o tabenasai. Eat more green peppers.  [~nasai is like the te form in that it gives commands, but it is stronger. ]

 

AND FOR THE:

{ motto ~ =  ~er }

もっと　早く　言って　下さい。 motto hayaku itte kudasai. (Next time) please say (it) a little earlier.  [Useful when someone tells you NOT to cut the yellow wire of the bomb after you have done that...]
