What does ity mean when used as a suffix?

The suffix "-ity" generally denotes state, quality, or condition. It is often added to adjectives or nouns to form abstract nouns.

Here are some examples:

* "Happy" (adjective) + "-ity" = "Happiness" (state of being happy)

* "Real" (adjective) + "-ity" = "Reality" (state of being real)

* "Pure" (adjective) + "-ity" = "Purity" (quality of being pure)

* "Secure" (adjective) + "-ity" = "Security" (condition of being secure)

* "Curious" (adjective) + "-ity" = "Curiosity" (quality of being curious)

However, there are some exceptions to this general rule:

* "Ability": This word comes from the Latin word "habilis" (meaning "skilled" or "capable"). It refers to the power or capacity to do something.

* "City": This word has its roots in the Latin word "civitas", meaning "citizenship" or "a community of citizens". It does not directly follow the "-ity" rule.

Overall, "-ity" is a versatile suffix that expands the meaning of words, adding a layer of abstraction to express states, qualities, or conditions.
