Final answer:
American English dialects vary among younger people, middle-aged individuals, and senior citizens. Pronunciations of ordinary words can vary accordingly.
Step-by-step explanation:
American English dialects vary among different age groups. Younger people, middle-aged individuals, and senior citizens may pronounce ordinary American words in slightly different ways. For example, the word 'grandmother' is often pronounced as [granmuthər] without the 'd' sound.
These variations can be seen through examples of rhotic and non-rhotic accents in different regions. Rhotic accents pronounce the letter 'r' before consonants and at the end of a word, while non-rhotic accents do not pronounce the 'r' sound in certain words.
By mapping dialects and completing dialect surveys, linguistic structures and cultural differences in American English can be identified. These differences are shaped by location, culture, ethnicity, and other factors.
