Both 'hacer falta' and 'necesitar' express necessity in Spanish, but they are used differently. ✅ NECESITAR → works like to need in English. The subject is the person who needs something. 👉 Necesito ayuda. (I need help.) ✅ HACER FALTA → literally means to be needed. The thing needed becomes the subject of the sentence. Structure: 👉 (Indirect object) + hacer falta + noun / infinitive Me hace falta dinero. (Money is needed for me → I need money.) ⚠️ Very important: singular → hace falta plural → hacen falta 👉 Me hacen falta dos días más.
