Final answer:
The word 'samsung' in the sentence should be capitalized as 'Samsung' since it is a proper noun referring to the brand name of the computer.
Step-by-step explanation:
Capitalization means using capital, or upper-case, letters. Capitalization of place names, family names, and days of the week are all standard in English. Using capital letters at the start of a sentence and capitalizing all the letters in a word for emphasis are both examples of capitalization.
Capital letters are useful signals for a reader. They have three main purposes: to let the reader know a sentence is beginning, to show important words in a title, and to signal proper names and official titles. 1. Capitals signal the start of a new sentence.
The word in the sentence that is incorrectly capitalized is 'samsung.' The correct sentence should have Samsung capitalized since it is a proper noun, referring to a specific brand name. Brand names always need to be capitalized. Therefore, the corrected sentence should be, 'I just bought a new Samsung computer.'
