Usage tips
Strong vs. weak
This verb has two conjugations. The meanings 'Platz machen' (to make room / give way) and 'nachlassen' (to subside / give way) are strong verbs (wich, ist gewichen). The meaning 'weich machen' (to soften) is a weak verb (weichte, hat geweicht).
EXAMPLE
Die Angst wich langsam der Erleichterung.
The fear slowly gave way to relief.
Giving way + dative
In the meaning 'Platz machen' (to make room / give way), the thing or person one gives way to is often in the dative. The auxiliary verb for forming the perfect tense is 'sein' (to be), because it describes movement or a change of location.
EXAMPLE
Der Fußgänger musste dem Fahrradfahrer weichen.
The pedestrian had to give way to the cyclist.
Figurative meaning
When the strong verb 'weichen' (to give way) is used with abstract nouns such as 'Angst' (fear), 'Zweifel' (doubt), 'Farbe' (color), or 'Spannung' (tension), the figurative meaning 'nachlassen' (to subside) or 'verschwinden' (to disappear) is meant.
EXAMPLE
Nach dem Streit wich die Anspannung einer peinlichen Stille.
After the argument, the tension gave way to an awkward silence.
Fixed expression
The idiom 'jemandem nicht von der Seite weichen' means to always stay with someone and support them. The person one stays with is in the dative.
EXAMPLE
In der schweren Zeit ist er seiner Familie nicht von der Seite gewichen.
During the difficult time, he did not leave his family's side.
Connection to 'weich'
The weak form 'weichen' (weichte, hat geweicht) is directly related to the adjective 'weich' (soft). It literally means to make something soft or let it become soft, usually through liquid.
EXAMPLE
Man sollte die Bohnen über Nacht in Wasser weichen lassen.
You should let the beans soak in water overnight.
