Andalusian Spanish is a way of speaking Spanish that is used in the southern part of Spain called Andalusia. It is different from other Spanish dialects in the way that some words are pronounced and the way that sentences are formed.
For example, in Andalusian Spanish, the letter "s" is often not pronounced, so instead of saying "gracias" (thank you), they might say "gracia". They also tend to use a lot of contractions, which means they'll put two words together into one word. So instead of saying "no tengo" (I don't have), they might say "notengo".
Another interesting thing about Andalusian Spanish is that they use a lot of "vosotros" which is the plural of "tú" (you). In other Spanish-speaking countries, it is more common to use "ustedes" instead of "vosotros".
Finally, Andalusian Spanish has a really unique and lively intonation, which means they use different pitch and volume when speaking. It can make their speech sound more expressive and passionate.
Overall, Andalusian Spanish is a fun and different way of speaking Spanish that you might hear if you ever travel to southern Spain.
