The suffix that determines capitalization is the proper noun suffix. Proper nouns are specific names of people, places, or things, and they are always capitalized. When a common noun is changed into a proper noun by adding a suffix, the capitalization is determined by the suffix. For example, the common noun "river" becomes the proper noun "Mississippi River" when the proper noun suffix "River" is added, and "River" is capitalized. **

The suffix '-able' would fit if you want to create an adjective that means "capable of being" or "having the ability to." This suffix is commonly used to form adjectives from verbs, such as 'comfortable' from 'comfort' or 'predictable' from 'predict.' **

The CIDR suffix is a notation used in CIDR (Classless Inter-Domain Routing) to indicate the number of bits used for the network portion of an IP address. It is represented by a forward slash followed by a number, such as /24. The number after the slash indicates the number of bits in the network portion of the IP address. For example, in the CIDR notation /24, the first 24 bits of the IP address are used to identify the network, while the remaining 8 bits are used to identify individual hosts within that network. **

You attach a suffix to the end of a word to change its meaning or function. The specific suffix you attach depends on the desired outcome. For example, if you want to make a noun plural, you would attach the suffix "-s" or "-es" depending on the word. If you want to make a verb past tense, you would attach the suffix "-ed" or "-d". It is important to understand the rules and patterns of suffix attachment in order to use them correctly in writing and speech. **

Some words that have the suffix 'tum' include "wisdom," "custom," "momentum," and "quantum." This suffix is often used to form abstract nouns indicating a state, condition, or quality. It is derived from Latin and is commonly found in English vocabulary. **

Suffixes are an important part of English grammar and vocabulary, as they allow for the creation of new words and the modification of existing ones. **
