Usage of っぺら and っぺらい


Are both っぺら and っぺらい used in the same way to emphazise an adjective? Is there
any difference between them?

For example: 薄っぺら/薄っぺらい

Can you use っぺら and っぺらい to every adjective?




You are asking as if っぺら(い) were a kind of suffix, but it's not a suffix that
can emphasize something. Actually, the only adjective I can think of that
contains っぺら(い) is 薄っぺら(い).

Regarding 薄っぺらな (na-adjective) vs 薄っぺらい (i-adjective), yes, they are
interchangeable and have the same meaning. There is a slangy i-adjective
[ペラい](http://zokugo-dict.com/29he/perai.htm), but this is never used as a na-
adjective (ペラな is wrong).
