Synonym discussion
Sense: adverb/1
Precisely is useful when you want to show an exact match. Exactly is the closest everyday synonym and works in most of the same places, but precisely often sounds a little more careful or formal, especially in explanations. Accurately focuses on being correct after measuring, describing, or reporting something, so it is closer to sense 4 than to sense 1. Specifically narrows the topic to one item or detail, rather than stressing a perfect match. Just can sometimes replace precisely before numbers or times, but it is much more informal and also has many other meanings. You can say 'The train left precisely at 7:05,' 'Please describe the damage accurately,' or 'What specifically worried the parents?'
Etymology
Precisely was formed in English from precise and the adverb ending -ly. Precise came through French from Latin praecisus, a word that originally suggested something cut off clearly. Over time, the idea developed into modern meanings such as exact, sharply defined, and careful in detail.
