sameish

Basically the same; somewhat similar; rather alike.

They all look alike, have about the same tone and the same color, and indeed they are very sameish all around.

Dressed like my mother, except all in green—green knit top, sameish green trousers.

Run-of-the-mill; ordinary; usual.

Otherwise, with the sameish meals and the utterly sameish pattern, the patternless days, I might lose count, lose my bearings, they might trick me.

Undergraduates are grouped in rather sameish groups to do rather sameish things. You are there because you fit in.

Dull; drab; boring; typical; not exciting.

For example, readers might say they love a post you've written on headlines, because they're finding that their headlines are becoming stale and “sameish.”
