Give instructions for a Polish native speaker on how to pronounce ll in Spanish.
To correctly pronounce the ll sound in Spanish as a Polish native speaker, follow these instructions:

1. In many Spanish-speaking countries, the ll sound is pronounced like the English y sound, as in the word yes. This pronunciation is called yeísmo. In Polish, this sound is close to the j sound, like in the word ja (I).

1. To produce the ll sound, place the tip of your tongue against the upper front part of your mouth (behind your upper front teeth) without touching it, just like you would for the English y sound or the Polish j sound.

1. Keep your tongue relaxed and slightly away from the roof of your mouth.

1. Start to produce a sound by pushing air through the small gap between your tongue and the roof of your mouth. It should sound like the y in yes or the j in ja.

1. Practice this sound in Spanish words containing ll, such as llamar (to call), lluvia (rain), or pollo (chicken). Remember to pronounce the ll as the y in yes or the j in ja.

Note: In some regions of Spain and South America, the ll sound may be pronounced differently. In these areas, it may sound like the English j in jump or the zh sound in the French word jardin. However, the yeísmo pronunciation is the most widespread and is usually understood by all Spanish speakers.
