Every alphabet needs a scientist. In Alphabet Harbor, it's Understanding U. And he wants to invent the world's stickiest glue.
Understanding U is such a unique letter. Usually, 'u' is a vowel, but he also serves as a consonant. Whenever he stands next to 'q,' the two together, 'qu,' say 'kw.'
As a vowel, Understanding U has three sounds, more than the others. He says one short sound and two long ones. We can hear these in the words, "up," "glue," and "you." Yes, one of u's long sounds 'yoo' is distinct from his other long sound 'oo'. Compare "cute" with "tube."
