Frequently Asked Questions
What is the difference between 'tercer' and 'tercero'?
They both mean 'third,' but 'tercer' is the required short form used only when it comes immediately *before* a singular masculine noun (e.g., 'tercer paso'). 'Tercero' is used when the word stands alone or comes *after* the noun (e.g., 'el paso tercero' or 'Él fue el tercero en llegar').
Does 'tercer' ever change for plural nouns?
No. When referring to plural masculine nouns, you use the full plural form: 'terceros' (e.g., 'los terceros pisos' - the third floors). 'Tercer' is strictly singular.
