* Accents are regional variations in pronunciation. Greek, while having regional variations, doesn't have the same kind of wide-ranging, distinct accents you find in English (e.g., Southern drawl, Boston accent).
* Greek has a distinct intonation system. Instead of accents, Greek uses a system of tones to change the meaning of words. There are three main tones: acute (high), grave (low), and circumflex (high-low). This system is similar to what you find in languages like Mandarin Chinese.
* Regional variations are often subtle. While regional variations exist in Greek, they mostly involve differences in vowel pronunciation, stress placement, and the use of certain sounds. These variations are often less pronounced than the major accent differences you find in English.
Think of it this way:
* English: You might hear a person from New York City speak very differently than a person from Texas.
* Greek: You might notice someone from Crete pronounce certain vowels slightly differently than someone from Athens, but they'll still generally understand each other.
So, while there are regional variations in Greek, it's more accurate to say it has a tonal system rather than specific accents.
