Unwanted Similarity: ～っぽい

っぽい is typically used with adjectives and nouns to give your verdict on something based on how something looks or acts. Used with i-adjectives the final い of the adjective is dropped.

安やすっぽい鞄くつ。

A cheap-looking bag.

Context: Regardless of the price, you think the bag looks cheap.

It can simply be added to nouns.

子供こどもっぽい。

Childish.

っぽい almost always carries a negative connotation and so the following is unnatural:

おいしっぽい食たべ物もの！(✘)

[Delicious-looking food.]

Here we would use 〜そう instead.

おいしそうな食たべ物もの。

Delicious-looking food.

You may also see it used with the verb “to be angry” and “to forget”. Here we need the verb stem.

怒おこりっぽい。

Short-tempered.

忘わすれっぽい。

Forgetful.

While not “proper” Japanese, young people may attach it to the end of the standard form of the verb as a sort of colloquialism.

彼女かのじょが悩なやんでいるっぽい。

Something seems to be bothering her.
