What is the difference between 'significantly' and 'slightly'?
Both describe extent, but they sit at opposite ends. 'Significantly' means to a large, noticeable, or important degree — enough to matter. 'Slightly' means to a small, barely noticeable degree. Saying prices rose significantly suggests a real, meaningful jump; saying they rose slightly implies only a minor change.
Does 'significantly' always mean 'statistically significant'?
No. In everyday English, 'significantly' simply means to a noticeable or important extent. In statistics it has a stricter, technical meaning — a result unlikely to be due to chance. The two overlap but are not identical, so a change called significant in conversation is not automatically significant in the scientific sense.
What is an example of 'significantly' in a sentence?
It usually modifies a verb or adjective to stress scale: 'The new engine is significantly more efficient,' or 'Sales improved significantly after the launch.' In each case it signals that the difference is large enough to notice and to matter, not a trivial or marginal amount.
