Briefly explain ambiguity and parsing and one common misconception about it.

# Ambiguity and Parsing **Parsing** is the process of analyzing a sequence (like a sentence or code) according to grammatical rules to determine its structure. **Ambiguity** occurs when a sequence can be parsed in multiple valid ways, leading to different interpretations. For example: - "I saw the man with the telescope" (Who has the telescope—me or the man?) - In programming: `if (x) if (y) foo(); else bar();` (Which `if` does the `else` belong to?) ## Common Misconception **Misconception**: "Ambiguity is rare and only occurs in poorly designed languages." **Reality**: Ambiguity is extremely common in natural language and even appears in well-designed formal languages. Most programming languages have inherent ambiguities that are resolved by precedence rules, associativity conventions, or explicit disambiguation strategies (like the "dangling else" rule). Natural language is pervasively ambiguous—our brains just resolve most ambiguities automatically using context, making us unaware of them.
