íssimas

íssimas is a suffix in Portuguese used to form superlatives. It is added to the end of adjectives to indicate the highest degree of a quality. For example, the adjective "belo" (beautiful) becomes "belíssimo" (most beautiful). The suffix can be attached to most adjectives, although some irregularities exist. The superlative formed with -íssimo is absolute, meaning it expresses the highest degree of the quality without comparison to other items. This form is commonly used in both spoken and written Portuguese to add emphasis and express intensity. The suffix changes its ending to agree in gender and number with the noun it modifies. Thus, "belíssimo" becomes "belíssima" (feminine singular), "belíssimos" (masculine plural), and "belíssimas" (feminine plural). Other common examples include "fortíssimo" (very strong), "altíssimo" (very high), and "novíssimo" (very new). The usage of -íssimo is widespread and contributes significantly to the expressive capacity of the Portuguese language.
