The suffix toco is defined as?

The suffix "-toco" is not a common standalone suffix in English. It's likely you're thinking of a different word or combination.

It's possible you're referring to:

* "toco-" - This is a prefix, not a suffix, meaning "childbirth" or "labor." It's commonly seen in medical terms, such as tocophobia (fear of childbirth).

* "toco" - This might be a misspelling of "toco-", the prefix mentioned above.

Can you provide more context or the word you're interested in? This will help me clarify the meaning.
