preciza

Preciza is about exactness of measurement or description; ĝusta is about being right. A wrong answer can be precise, and a right one can be vague, so the two are not swappable. The adverb precize is very common and often means "exactly" in the conversational sense of agreeing with someone. Do not confuse it with precipe, which means especially and looks nearly identical - one letter and one syllable apart, and a genuine reading trap. Precizeco gives precision, malpreciza gives vague.
