Thanks for your reply.

What does prem/prim mean?
bi(two), tri(three).
Thanks.

Prem or prim... can be a prefix for primative or premature

The prefixes aren't "prem-" or "prim-" -- it's "pre-"

Look up pre*

"prim-" as a prefix will lead you nowhere. "Primary" and "primitive" are two words with "prim" at the beginning, but it's not a prefix; it's part of the root word, from primus in Latin:

You're welcome! The prefixes "prem" and "prim" both have meanings related to numbers.

The prefix "prem" refers to the number one. So, words like "premiere" and "premier" are derived from "prem" and they mean the first or the earliest.

On the other hand, the prefix "prim" refers to the number two. For example, words like "primary" and "primarily" are derived from "prim" and they mean first in importance or mostly.

To find the meanings of these prefixes, you can consult different resources such as dictionaries or online linguistic references. These sources provide clear definitions and explanations for various prefixes, including "prem" and "prim".
