on the [ADJ] side

1 The phrase on the [ADJ] side is just another way of saying kind of [ADJ] — especially in the spoken language. It's common to all varieties of English, not just American. Like kind of, it tends to sound a bit cautious; we use it when we don't want to sound too categorical or critical of someone of something; when we want to be honest, but not too direct.

Angie's trying out a new soup recipe on her husband.

____________

Angie: How's the soup? I got the recipe from my sister.

Thomas: It's, uh... really good!

Angie: You don't sound too convinced.

Thomas: No, I like it. It's just a little on the salty side.

Angie: I think you're right. I used twice as much bacon as the recipe called for and I should've adjusted it for salt.

Note that this phrase is often preceded by adverbs like a little, a bit, somewhat... again, in the spirit of not sounding too categorical and critical.

Gary's on a flight to London and notices the man sitting next to him is reading Interview with The Vampire, which he's never gotten around to reading.

Gary: Hey, how are you liking that book? I've been meaning to read it forever. My sister swears by it.

Don: Yeah, it's longish and a little on the corny side. Lots of emotional rants and drawn-out descriptions of what the characters are feeling, etc. But on the whole, it's a pretty entertaining story.

Gary: Ugh, thanks for the warning! I think I'll just watch the movie.
