I was recently having a conversation with my mother, who is Spanish-speaking only, after she was informed by someone who only spoke English that some work was going to be done on her street on the 20th. However, there was some confusion on both sides, because she had thought they said, 28th. She asked, '28th?' And the guy said, 'Yeah.' So, she assumed it really was the 28th. Come to later find out that they actually meant the 20th! She was wholy unprepared for their visit and tried her best to adjust her plans accordingly. In an attempt to explain the possible confusion, I tried to explain some equivalent pronunciations that people would use in Spanish for ordinal numbers like primero, segundo, tercero, etc., but I couldn't find any for 20 and beyond. I'm not sure how well she understands the English way of pronouncing numbers like that, though given that 20th and 28th might sound very similar, as well as any number like 40th or 50th, still, such instances might be rare.
I'm wondering if there are some good resources or simple explanations or analogies that my mother could benefit from, so that hopefully the mistake won't be repeated.
