what is a "string" in bash?

i keep hearing people talking about "strings"? what is a string? what are people talking about? i keep hearing "enter a string" or "if your string this" or your "string that"? what does it mean to enter a string in bash? any help would be appreciated, i'm genuinely confused at what it's supposed to mean when i ask google it tells me "Bash String is a data type similar to integer or boolean. " and i have no idea what this is supposed to mean thank you
