aðar

Açar is a Portuguese verb that designates the action of sharpening or whetting a blade or tool. It is considered archaic or regional and is not common in contemporary standard Portuguese, where afiar or afi ar is usually preferred. The term appears in older texts and in some dialectal registers, especially within metalworking or crafts contexts.

Usage of the verb is primarily historical or regional. In modern writing, açar can be encountered in descriptions of traditional tool maintenance or in dialect writing. Examples: “O ferreiro açou a lâmina” and “Ela açou o fio da faca com a lima.” Because of its rarity, many speakers would opt for afiar instead.

Conjugation (present and imperfect, regular -ar pattern with the ç- stem):

- Present: eu aço, tu aças, ele/ela aça, nós açamos, vós açais, eles/elas açam.

- Imperfect: eu açava, tu açavas, ele/ela açava, nós açávamos, vós açáveis, eles/elas açavam.

Synonyms and related forms include afiar and afiar o fio. Açar, when used, is typically restricted to historical, regional, or technical contexts rather than everyday speech.

See also: afiar, ferramentas, ferraria.

Etymology: the exact origin is uncertain. It is commonly linked, at least etymologically, to aço (steel) or related metalworking terms, suggesting a historical association with sharpening steel and blades.
