ideal vs wirklich
really
'wirklich' and 'ideal' can form a contrast when it comes to reality and imagination. 'wirklich' describes something that is real or actually exists. 'ideal' can mean that something exists only as an idea or an imagined ideal and is not present in reality. This contrast is important when distinguishing between a real state and a perfect picture in your mind. In other meanings, 'ideal' is not the opposite of 'wirklich', for example in 'eine ideale Lösung' (an ideal solution) in the sense of 'perfectly suitable'.
ideal
In der idealen Welt hat jeder genug Zeit und Geld.
In the ideal world, everyone has enough time and money.
wirklich
Die Gefahr war wirklich, auch wenn sie am Anfang klein wirkte.
The danger was real, even if it seemed small at first.
