Capitalization Using uppercase for the initial letter of a word and lowercase for the rest of the letters Lowercase letters are used in all of the words. "The dam has burst," says the sentence. This case format is used in several sub-titles. Uppercase letters are used for proper nouns. "The president" "a king" "my friend." These are all examples of upper case usage. Words that are common names or phrases can be capitalized. "My name is Bob." "The store was crowded." Both these sentences are written in first person singular (I) present tense. Therefore, they need to use the verb form "is" with an object marker ("a/the") followed by a gerund (-ing form of the verb). The gerund here is shown by the -ing suffix attached to the end of the word "is". To write this sentence correctly, we would need to know what form "Bob's name" takes. In this case, it is not a real word so it is considered a noun. Thus, it needs to be capitalized like any other noun. "My name is Bob." Finally, some words are always capitalized regardless of their function. These include articles, adjectives, adverbs, pronouns, conjunctions, and verbs.
