Usage tips

The sky over the desert seemed to be boundless.

grenzenlos vs endlich
finally / finite
'endlich' and 'grenzenlos' are opposites here. 'endlich' means that something is limited and has an end. 'grenzenlos' means that something has no clear limits or is felt to be infinitely large. You can contrast them in abstract topics such as time, possibilities, or feelings. 'endlich' can be confusing because in everyday language it often means 'after a long wait' or 'finally'. In this pair, however, it is not about waiting, but about limitation. As a memory aid: 'endlich' has a limit; 'grenzenlos' has none.
grenzenlos
Nach dem Erfolg war ihre Freude grenzenlos.
After the success, her joy was boundless.
endlich
Die Vorräte sind endlich, deshalb müssen wir sparsam damit umgehen.
The supplies are finite, so we have to use them sparingly.
