Note
1) Easy to confuse with ~まで.
→ ~さえ means 'even...', emphasizing something unexpected; it's not the 'up to/extent' limit.2) Easy to confuse with ~しか.
→ ~さえ: adds (even...).
→ ~しか: restricts and always used with negation.3) If used in the conditional form (~さえ…ば), it has a different meaning.
→ With ~さえ…ば it's often 'as long as/just... then...', so check the structure.
