How circum- works

The prefix 'circum-' attaches most commonly to Latin verb or noun bases without spelling change, as the final 'm' is stable and does not assimilate to the following consonant the way 'in-' does. It can turn verbs into more directionally specific verbs (navigate → circumnavigate) or contribute to nouns and adjectives describing surrounding conditions.

Watch out: The word 'circumcise' genuinely contains the prefix, but 'circus' does not—it comes directly from Latin 'circus' (ring, circle) without the separable prefix 'circum-' attached to another base.
