Grundlage vs Basis
basis / base
'die Basis' and 'die Grundlage' are often very similar. Both mean something on which something else is built, for example knowledge, a decision, or a plan. 'Grundlage' sounds very natural in many everyday situations and in official texts, especially with rules, information, or decisions. 'Basis' can fit just as well, but sometimes sounds a bit shorter or more technical. They are easy to confuse because the phrases 'auf der Basis von' (on the basis of) and 'auf der Grundlage von' (on the basis of) also work almost the same way.
Grundlage
Die neuen Zahlen sind die Grundlage für unsere Entscheidung.
The new figures are the basis for our decision.
Basis
