Bug words that are not insects

Not every bug on List 3 is an insect.

Ladybug and mealybug are insects; a doodlebug is an antlion's larva.

Questions and answers

Can I print an ug word family worksheet?

Yes. Choose one of the three lists and print it as a word list with a sentence for each word, a test sheet, an ABC order sheet or a missing letters sheet.

What vowel sound do ug words have?

Short u, the vowel of cup and sun. The American Heritage Dictionary writes it ŭ, so bug is (bŭg) and shrug is (shrŭg).

Is dug an ug family word or a form of dig?

Both. Dug rhymes with bug and belongs on List 1, and it is also the past tense of dig, so the vowel changes from short i to short u: I dig today, I dug yesterday.
