- Add the standard future/conditional endings to that new stem.
- The stem is identical for both the Future and Conditional tenses.

Smart Tips
Check if it's one of the 12 irregulars before adding the ending.
Always use the conditional form of 'poder' or 'querer'.
Use the future tense for certainty, not just 'ir a'.
If you don't know the irregular stem, use 'ir a' + infinitive.
발음
Consonant clusters
The 'dr' sound in 'tendr-' requires a crisp 'd' followed by a rolled 'r'.
Conditional request
¿Podrías...?
Rising intonation at the end to sound polite.
암기하기
기억법
Remember the 'D-R-N' rule: Many irregulars add a 'd' (tendr, pondr, saldr, vendr, valdr) or an 'r' (querr, har).
