What part of speech is the suffix cal?

The suffix "-cal" is not a part of speech on its own. It's a suffix, which means it's added to the end of a word to modify its meaning or create a new word.

Here's how it works:

* Function: The suffix "-cal" typically forms adjectives from nouns.

* Meaning: It usually indicates relating to or pertaining to.

Examples:

* Music (noun) + -cal = Musical (adjective) - relating to music

* Physic (noun) + -cal = Physical (adjective) - relating to the body

* Logic (noun) + -cal = Logical (adjective) - relating to logic

Therefore, to understand the part of speech of a word ending in "-cal", you need to consider the entire word.
