Spanish adjectives can be broadly divided into two groups: those whose lemma (the base form, the form found in dictionaries) ends in "-o", and those whose lemma does not. The former generally inflect for both gender and number; the latter generally inflect just for number. "Frío" ("cold"), for example, inflects for both gender and number. When it is used with a masculine singular noun, the masculine singular form "frío" (the lemma) is used. When it is used with a feminine singular noun, it becomes "fría"; "-a" is generally the feminine singular ending for adjectives that inflect for gender. When it is used with a masculine plural noun, it becomes "fríos", and when it is used with a feminine plural noun, it becomes "frías"; "-s" is the plural marker for both the masculine and feminine with adjectives that inflect for gender.
