This document discusses evidence for phrases from native speaker intuitions. It provides 3 key pieces of evidence:
1. Native speakers have intuitions about the existence of words, phrases, and syntactic categories like word-level and phrasal categories. Phrases are not all the same kind.
2. The substitution test shows that pronouns can substitute for phrases that appear in different positions in a sentence, indicating they form constituents.
3. The movement test involves moving constituents to the front of the sentence. For example, "Those fried green tomatoes, the chef cooked" is grammatical but "*Tomatoe, the chef cooked" is not, showing "those fried green tomatoes" forms a constituent.
