The poem discusses how vowel pairs are pronounced in English words. When two vowels go side by side, the first vowel makes the dominant sound and the second vowel has little to no sound. Some examples given are that "OA" makes an "O" sound in words like "goat" and "boat", while "AI" makes an "A" sound in words like "train" and "rain". The poem reinforces that the first vowel "does the talking" and is the sound we hear, while the second vowel "steers clear of our ears".
