B to BR stem changes in the Spanish Future Tense affect certain verbs when expressing future actions or states. This change involves adding an ‘r’ after the ‘b’ in the infinitive before attaching the future tense endings.
A key example is ‘saber’ (to know), which becomes ‘sabr-‘ in the future tense. Thus, ‘sabré, sabrás, sabrá,’ etc. This change applies to ‘saber’ and some of its compound forms.
