What does insurmountable mean?
Insurmountable means impossible to overcome, defeat, or get past. It is used especially for major difficulties, obstacles, barriers, and challenges: an insurmountable problem cannot be solved by the methods currently available, while an insurmountable obstacle blocks progress altogether. The word is formal and carries a strongly absolute implication, suggesting that the situation requires a fundamental change rather than greater effort alone. In everyday conversation, people sometimes use it loosely for something that seems very difficult, though its literal meaning is stronger. It is especially common in formal discussion of politics, law, finance, education, and personal or professional obstacles. Because the term suggests a limit that cannot be crossed, it is often paired with nouns such as “challenge,” “difficulty,” “barrier,” and “obstacle.”
adjectiveImpossible to overcome or surmount. Used of difficulties, obstacles, barriers, and other challenges that cannot be overcome by ordinary means.

Its relatives include insuperable and superable, while irresistible shares the root sense of being unable to be overcome or resisted.
