The word 'hombro' for 'shoulder' is standard and universally understood across all Spanish-speaking countries, including Mexico, Colombia, Argentina, and Spain. There are no common regional alternatives.
Saying 'Mi hombro duele' instead of 'Me duele el hombro'. — In Spanish, pain is expressed differently. The verb 'doler' works like 'gustar'. The thing that hurts is the subject, and the person is the indirect object. So, it's 'Me duele el hombro' (The shoulder hurts me).
Pronouncing the 'h' at the beginning of 'hombro'. — The letter 'h' is always silent in Spanish unless it's part of 'ch'. The correct pronunciation is 'OM-broh', not 'hom-broh'.
Using the wrong gender, like 'la hombro'. — 'Hombro' is a masculine noun. Always use the masculine article 'el' (the) or 'un' (a). For example, 'el hombro' or 'un hombro'.
