Learn English – words to describe unqualified person

If you're frightened of dogs, I would recommend you say that and not say "I'm not a dog person." Saying that you're not a dog person implies that you just dislike dogs for some reason. A dog owner might try to change your feelings by getting you to engage with their dog, because they can't imagine anyone disliking the pet that they find so appealing. If you say "I'm scared of dogs.", most dog owners will understand that is not something that you can easily change your mind about, even if their pet is a really nice dog.

Here's another example: if my friend and I are talking about food and I say "I'm not a shrimp person.", my friend might say "Oh that's just because you've never tasted MY shrimp recipe that everyone says is really good! I'll make some for you tomorrow." If I had said "I'm allergic to shrimp.", my friend might say "Oh that's too bad - I have a really great recipe for shrimp. Maybe I'll try it with chicken next time so you can taste it."

When you tell someone that you don't like something that they themselves like, it's just human nature to try to persuade you over to their point of view.

It depends in part what you're describing and if there is already a pattern established for such positions, for example, in anatomy, anteromedial combines front and center.

But assuming there is no pattern, I would use the usual adjective suggestions: use the main adjective and modify it with the other.

On a written page, we usually describe something's placement as in the "upper left corner" rather than "left upper corner". For a crowded room, I would use front left, rear left, front right, rear right.

On the other hand, describing pockets, the side usually comes first: left front pocket, right front pocket, etc.

So, the context of what position you're trying to refer to matters.
