〜っぽい: '-ish' / '-like' / 'Tends To' (Meaning + Examples)

What it means

〜っぽい is a colloquial suffix that adds the feeling of "has the qualities of" or "gives off the impression of." Think of English "-ish" or "-like": childish, watery, cheap-looking. It attaches to two main things:

• a noun → "has the qualities of that thing" (子供っぽい = childish)
• a verb's ます-stem → "tends to / does it easily" (忘れっぽい = forgetful)

Because it describes an impression, it leans subjective and casual, and it usually has a slightly negative or judgmental edge.

How to form it

You drop nothing — just glue っぽい onto the base. The result is a normal い-adjective, so it conjugates like 高い.

The key takeaway: っぽい is an い-adjective, not a noun. Once it's attached, treat the whole word exactly like 高い or 新しい.

Noun + っぽい — "having the qualities of"

With a noun, っぽい means the thing resembles or gives off the vibe of that noun, even though it isn't really it:

ます-stem + っぽい — "tends to / easily"

With a verb stem, っぽい describes a habit or tendency — the person/thing does it readily, often more than you'd like:

Common members of this family: 忘れっぽい (forgetful), 怒りっぽい (quick to anger), 飽きっぽい (gets bored easily), 湿っぽい (damp / gloomy).

"Looks like / seems" — the colloquial use

In casual speech っぽい also works like a quick "seems / looks like," tacked onto a noun or even a clause:

You'll hear young speakers say 雨っぽい ("looks like rain") or 帰ったっぽい ("seems like they went home"). This last clause-attaching use is very colloquial — fine in conversation, not for writing.

っぽい vs らしい vs 〜がち

These three overlap in English ("-like," "tends to"), but the nuance differs:

• っぽい — resembles / has the qualities of, often critically. 子供っぽい = childish (negative: immature).
• らしい — is typical of and lives up to it, usually positive. 子供らしい = childlike in a good, age-appropriate way. (See the らしい guide.)
• 〜がち — leans toward a (usually unwanted) tendency, more neutral/formal than っぽい. 忘れがち = prone to forgetting.

So 男っぽい = "mannish/butch" (an impression), while 男らしい = "manly" in the admirable sense. The tone flip is the whole point.

Common mistakes

1. Treating っぽい as a noun. It's an い-adjective: say 子供っぽい人, 子供っぽくない, 子供っぽかった — never 子供っぽいの人 or 子供っぽいだ.
2. Mixing it up with らしい. 子供らしい is praise ("nicely childlike"); 子供っぽい is a jab ("immature"). Don't compliment someone with っぽい.
3. Forgetting it's casual. In essays or business writing, prefer 〜がち or 傾向がある over っぽい for "tends to."
4. Using を/だ after a verb-stem form. 忘れっぽい is already an adjective: 忘れっぽいです (✓), not 忘れっぽいだ in polite speech, and never 忘れっぽする.

Quick recap

• Noun + っぽい = -like / having that quality (子供っぽい, 水っぽい).
• ます-stem + っぽい = tends to / does easily (忘れっぽい, 怒りっぽい).
• It's an い-adjective: っぽくない, っぽかった, っぽくなる.
• Casual, with a usually critical tone — contrast らしい (positive) and 〜がち (neutral tendency).
