Saying 'Llamen una ambulancia' instead of 'Llamen a una ambulancia'. — In Spanish, the verb 'llamar' (to call) is almost always followed by the preposition 'a' when you are calling a person or a service for help. Think of 'llamar a' as a set phrase meaning 'to call upon'.
Using the noun 'teléfono' as a verb, like 'Teléfono una ambulancia'. — 'Teléfono' is a noun meaning 'telephone'. The verb for 'to call' is 'llamar'. Always use 'llamar' or 'llamen' (the command form).
Mispronouncing 'llamen' as 'LA-men'. — The double 'll' in Spanish typically makes a 'y' sound, like in the English word 'yes'. So, 'llamen' is pronounced 'YAH-men'.
