Don't parrot your grammar book — trust your native speaker judgment! This new poster in the National Linguistics Effort series is based on a vintage design. The text at the bottom says “This poster is published by Cascadilla Press as a contribution to the National Linguistics Effort.”
This poster is available in our shop on Cafepress. Other posters in our vintage series include Loose Lips Make Bilabial Trills, Strong Verbs for a Strong America! and Linguists Need Data!
